I'm getting a new lappie

[Brooke W]

My dad got one for me (us, being dh and I, but he and I both know who'll be using it,lol). Not sure what it looks like or anything else but that it's a compaq/hp. I'm not complaining, I'm excited to have one at all,lol. AND, he's going to be sending me his PS7 because it's for Windows and he switched back to a Mac.
Here's my question. Will I be needing a router since I'm going to now have two machines? Can't spend a whole lot of money but would like advice on the things one should have when you have a desktop and a laptop.
I also am thinking seriously about getting a mouse for it, as well as one of those laptop cooling systems.
So, besides all that, what else would you suggest to add, need, etc?

Also, he got the upgrade to Vista and I'm going to have to install it (Hey, I happen to like Vista,lol). Is it hard to install a new OS? Warn me now, I need to, want to be, prepared,lol.
