I've never tried the Centos network install, but I'm pretty sure it is better than the tradition install, which I have done several times. In the traditional install, you spend a long time downloading the very large image of a DVD, then burn it to a DVD, then boot and run that. It then proceeds to go out to the network for almost all the software you select even though there are copies on the DVD. Maybe I always did something wrong. But it seemed like the process itself wasn't designed very well. If it is going to get everything from the net anyway during install, a small CD image should have been enough to start it (which is one of the ways you can do the Centos network install).
I just now googled Centos "network install"
. There were a bunch of helpful looking pages identified. None of the first few looked either official or better than the others. So you might do the same google search yourself and choose one you like. Or you might start at the centos.org download site and look for network install or some similar phrase.
Beyond that, all the steps of the install are pretty self explanatory as you do them, except you are likely (based on my experience with older versions) to be asked whether to install certain options before you have any info with which to make an informed choice. Don't worry about those details. All choices of whether to include a software package are easily reversed in either direction later once you know enough to make a better choice.

I think Centos is a bit large for VM on that hardware. I would suggest dual boot. But I think VM would also be usable, so I'm not certain which is best. If someone with more VM experience (than I have) suggest VM, you might be wise to trust them instead of me.
My experience with repartitioning after Vista or Windows 7 was installed is that best practice is to use Windows tools to shrink the existing Windows partitions (you could use the partitioning software on the Linux install CD, but that is not as good). Then leave the freed space unpartitioned and let the Linux install process create partitions (do not try to use the Windows partitioning software to create partitions for Linux).
1) Disable paging in Windows (optional, but it helps)
3) Defragment the partition in Windows (optional, but it helps)
4) Shrink the partition in Windows.
5) Reenable paging
6) Reboot again to verify everything is OK before trying Linux
7) Install Linux.
For Windows XP, step 4 must be done in Linux, but steps 1, 3 and 5 should still be done in Windows.
As I recall from older versions of the Centos installer, that installer walks you though the process of creating partitions and gives you more advanced choices than you really need, including more partitions than you should have for your situation. I think you only need a small SWAP partition (maybe 2GB) plus a / partition. You do not need boot or home or any of the other optional partitions.
Pay attention to be sure you are telling it to create new partitions in the space left unpartitioned by shrinking Windows and that you are not telling it to delete or reformat the existing Windows (and probably OEM) partitions. If you know the basic concepts of partitioning, that should be pretty obvious. But some people have made horrible mistakes at that point.
