He is in good hands here.
Vengeful, the kit that Silverion77 mentioned would be an excellent starting kit for a newbie. It is offerred in 3 flavors, the Compact (for strictly just CPUs), Apex-Ultra (while it is oferred as a solution for CPUs in its original packasge, it is very flexible and can handle additional waterblocks) and the Apex-Ultra+ (which is the all inclusive package for CPUs, GPUs and even the northbridge.
Now, it really depends on how you want to start out here as to what you might should get. However, all of this is predicated on what your actual budget is as well. We are talking about a price range from $150 for the compact to the rather hefty $350 for the Apex-Ultra+. If you spend enough time in this forum you will find out that it is bestter to steer clear of kits such as the one you mentioned earlier (the Galaxy) because of the rather weak craftsmanship and parts.
As far as installation, they come with instructions but it is easy enough to come here if you have any questions. Also, maintenance is something you can learn from here if the instructions are not clear enough. There are alot of good and knowledgeable people here with quite alot of experience at this sort of thing that would be perfectly glad to help you like Silverion77 has been doing.
