Grant Palin's questions

I'm intending to move my primary domain registration from its current location (my web host) to a separate registrar. Not because there's a problem with the current setup, but rather to have my domains all in one place. The web hosting is staying put (for now, anyway), it's just the domain registration being changed.

I've moved domain names around before, and know about changing the nameserver information to match wherever the site is hosted. The catch here is that I am using Google Apps for my domain. I'm aware there's some special setup to make that work, though I don't know the details. The host handled these details in the initial setup.

Are there extra steps involved in making Google Apps work with the domain when the domain name is moved? Or is it enough to just update the nameserver information on the new domain host?

EDIT: if it matters, the current registrar is Dreamhost, the target is Gandi.

I am currently on shared hosting, and have been recently looking at the idea of switching to a VPS instead. From what I have gathered, a VPS allows you more control over your server setup. But at the same time you have to set it up yourself, and maintain it. This is the bit I am asking about...

Despite the power and flexibility you get from using a VPS, you have to take care of it yourself. Is it worth it?

^{_{Some context: I am primarily a Windows user, but have been tinkering with various Linux distros off and on for several years. I know enough about Linux to get by, or to be dangerous - take your pick. I've also done some tinkering on my current host, but have no serious sysadmin experience. There's always a first time!}}
