Using the Juniper EX3300 Switch as a router?

So I have a Juniper EX3300 Switch. One of its uplink ports (ge-0/1/0) is connected to my ISP's router. ISP router's port address is xx.xx.xx.109. My switch's IP address is xx.xx.xx.110.

From the switch, I can ping to xx.xx.xx.109 and any other IP in the world. I mean its connected to the Internet.

I connected the port eth0 of a computer (running Ubuntu) to the port ge-0/0/0 of the switch (which in the same VLAN as ge-0/1/0). I configured the port eth0 as follows:

iface eth0 inet static
    address yy.yy.yy.208
    netmask 255.255.255.240
    gateway xx.xx.xx.110

yy.yy.yy.208 is assigned to me by the ISP. So, now I can ping to the switch (xx.xx.xx.110) from this computer. But I can not ping to either xx.xx.xx.109 (ISP router) or any other IP.

I want this computer to be connected to the Internet. What am I doing wrong?

Here are some of the configurations on my switch:

interfaces {
    ge-0/0/0 {
        unit 0 {
            family ethernet-switching;
        }
    }
    .
    .
    .
    ge-0/1/0 {
        ether-options {
            no-auto-negotiation;
            link-mode full-duplex;
            speed {
                1g;
            }
        }
        unit 0 {
            family ethernet-switching {
                port-mode access;
            }
        }
    }
    .
    .
    .
    vlan {
        unit 0 {
            family inet {
                address 10.0.1.1/24;
            }
        }
        unit 1 {
            family inet {
                address xx.xx.xx.110/30;
            }
        }
    }
}
.
.
.
routing-options {
    static {
        route 0.0.0.0/0 {
            next-hop xx.xx.xx.109;
            retain;
        }
    }
}
vlans {
    Cogent {
        vlan-id 3;
        interface {
            ge-0/1/0.0;
            ge-0/0/0.0;
            ge-0/0/1.0;
            ge-0/0/2.0;
            ge-0/0/3.0;
        }
        l3-interface vlan.1;
    }
    TFLan {
        vlan-id 2;
        interface {
            ge-0/0/5.0;
            ge-0/0/6.0;
            ge-0/0/7.0;
            ge-0/0/8.0;
            ge-0/0/9.0;
            ge-0/0/10.0;
            ge-0/0/11.0;
            ge-0/0/12.0;
            ge-0/0/13.0;
            ge-0/0/14.0;
            ge-0/0/15.0;
            ge-0/0/16.0;
            ge-0/0/17.0;
            ge-0/0/18.0;
            ge-0/0/19.0;
            ge-0/0/20.0;
            ge-0/0/21.0;
            ge-0/0/22.0;
            ge-0/0/23.0;
            ge-0/0/4.0;
        }
        l3-interface vlan.0;
    }
}

The routing on my Juniper EX3300 does not seem to be working. My ISP's gateway is at xx.xx.xx.xx. And I have the following in the configuration:

routing-options {
    static {
        route 0.0.0.0/0 {
            next-hop xx.xx.xx.xx;
            retain;
        }
    }                                   
}

I can ping to my ISP's gateway from the switch. However, I can NOT ping to any other IP. When I do a traceroute (to Google.com's IP). This is what I get:

traceroute to 74.125.224.69 (74.125.224.69), 30 hops max, 40 byte packets
traceroute: sendto: No route to host
 1 traceroute: wrote 74.125.224.69 40 chars, ret=-1
 *traceroute: sendto: No route to host

Do I need to enable any protocols? I guess this goes without saying, but I am kind of new to Junos.

Update: This is the output from show interfaces terse | match inet:

bme0.32768              up    up   inet     128.0.0.1/2

vlan.1                  up    up   inet     xx.xx.xx.110/30

and this is the output from: show route forwarding-table:

I have a Juniper EX3300 switch in a data center. And I have connected one of the uplink ports (ge-0/1/0) to my ISP's router. I want to configure it so that all the devices connected to ports in the same VLAN as ge-0/1/0 can access the Internet. I have done some research, and I haven't gotten anywhere really.

I have configured the interface as follows:

ge-0/1/0 {
    ether-options {                 
        no-auto-negotiation;
        link-mode full-duplex;
        speed {
            1g;
        }
    }
    unit 0 {
        family inet {
            address xx.xx.xx.xx/32;
        }
    }
}

where xx.xx.xx.xx is the "Customer Router Port IP" assigned by my ISP.

When I try to commit, I get the following error:

Interface ge-0/1/0.0 not enabled for switching

Can some one tell me what is the right way to configure it?

I have a Juniper SRX220 (junos) router where I have configured vlan.1 and vlan.2 with IP 10.0.1.1/24 and 10.0.2.1/24. Now I want to route between these networks. How do I configure that in Junos? I can't figure that out from the manual and it does not work out of the box.

In order to support desktop imaging requirements I need to correct the multicast design on an existing network, but am not well versed in this subject. The diagram below gives a basic example of the topology. The Juniper EX8200 is the hub in a simple hub and spoke design. It has 1Gb L3 interfaces directly connected to each of the other sites. OSPF is enabled on these interfaces to exchange routes with Cisco devices at the other sites. The hub and each site will have one or more VLANS trunked to closet switches. My understanding up to this point is that on each of the VLAN interfaces at each site, I should have both IGMP and IGMP-Snooping enabled. On the WAN connections, I should have PIM dense mode enabled on the Juniper side, and sparse-dense-mode enabled on the Cisco side. For the Juniper's directly connected VLANs, I'm unsure which mode to use, but since its the largest environment with the most clients, I would expect to simply use dense mode on all of them. So here are my questions:

1) Do I have to concern myself with assigning addressing anywhere here? 2) Are there any major flaws in this design?
