Well I don't know what distro would work best for laptops, but....
check out this site
It has 4 or so examples of people installing linux on a I8600 laptop. Read thru those and then you can get a feel for what you need to do.
Other then that "user friendly" distros are: Fedora/Redhat, Mandrake, Suse
Fedora is business oriented, Mandrake is bent on good home desktop, Suse is about new technology or something like that.
Just install whatever on it, and when you run into a problem see if that website can help you out.
Laptops can be a pain because each manufacturer likes to put twists and weird features on otherwise normally common hardware, and not tell anyone.
As far as wireless stuff goes, I don't know if you have a built in wireless card built in or not.
but if you haven't got a card and are looking to buy one, then check out
here and make sure you buy one that is compatable.
Getting one thats well supported with open source drivers will make your job a 150% easier then dealing with semi-compatable stuff. (edit: also check out long it's been supported. If it's something brand new in the last year or so, then their is a chance that the distro your using may not deploy it out of the box. Look at what steps you need to go thru to get stuff working.)
