IMO you are getting ahead of yourself. Don't even worry about installing Linux right now. Since you haven't picked a distro you need to do that first.
With the advent of the Live CD/DVD picking a distro is fun and easy. A Live CD allows you to boot Linux without installing it at all. Linux will run fine on a modern computer straight from a CD or DVD with no hard drive space all.
Ubuntu is the most popular distro, it is easy to use and is well supported.
Kubuntu is Ubuntu with a KDE desktop environment instead of Gnome.
Mint is based on Ubuntu and has a multimedia focus.
Personally I think all the distros listed above are a bit slow, but they do work fine and are very popular.
Sabayon is Gentoo based and is my favorite full sized distro. Sabayon is easy to use and runs faster than the Ubuntu variants.
Puppy is my very favorite distro (using Puppy now). Puppy is very lite and fast. It can load completely to RAM so in addition to being super fast it also cuts down on drive access.
At ~96MB to download Puppy is a must see. Even if you decide on a bigger/slower distro Puppy is still worth looking at. You will be amazed at how good/complete a ~96MB distro can be.
All the distros listed above have some sort of Package Manager that makes it easy to install new programs or update existing ones. Puppy's is called PETget. Keep that in mind if you like a distro but it seem to be missing something. Chances are whatever is missing can be downloaded.
