The manufacturer usually warrants them, not Newegg.
A PSU is the shorthand for "power supply unit" and that's what converts the power from a wall outlet into something that the PC can use. I'm sure you know that when you plug your power cord into the computer, it is always at the top of the tower and there's a switch on it and a smaller switch that allows you to switch between 120 and 240 volts (sometimes it's there, my Dell had it). What you're plugging the power cord into is the power supply unit. And yes, quite obviously, you do need one!
I wouldn't worry about breaking the pins or anything. The only thing you need to do is buy a static electricity reducer mat (you can find them at RadioShack) so that you don't accidentally shock and ruin one of your parts by static electricity. They're cheap and definitely worth it. When you install a CPU, just make sure which way it fits in is correct and gently set it where it needs to be. You don't have to push it or anything, it'll fall right down into its designated spot once you had it right. There is absolutely no need to force the processor down into the slot; if you have to press a bit then you do not have it in right. Just be very careful when installing it and you'll be perfectly fine.
You're about right on the mark for what you need to build a complete computer. Most motherboards come with onboard sound (which I'm using right now) so you don't really have to buy a sound card if you don't want to. It does improve your sound performance in games, though, and usually has more features and a lot more inputs. The optical drives I have in my computer are a DVD-RW and a regular old CD drive. I don't need anything else, really, unless I would be copying a DVD to DVD, but I never do that. A lot of motherboards also come with an ethernet (CAT5) port already in them; however, I'd recommend getting an ethernet card if you have a free PCI slot. My onboard ethernet began to malfunction a year or so after I had it where it would not hold a steady connection even though it said it was connected in Network Connections in the Control Panel. I'd be talking to my friend on AIM and surfing the web, and all of the sudden my AIM would log off and the Internet wouldn't work for like a minute... Stuff like that. So I recommend one. You can get USB ones, too.
I got some speakers for you! I have some JBL Creature II's and I love them! They have good bass response and crisp sound. They look strange, yes, but they sound really good. I'm thinking about getting some Logitech Z-2300's for my new computer that I'm building at some point. They'll run you at about 100 dollars, but they're THX certified and have 400 watts peak power and 200 watts RMS! They are 2.1 speakers. They also have really good reviews on Newegg.
The motherboard determines how many USB ports you'll have. Usually you have two in the front of your case which you can hook up to the motheboard.
Mobo = motherboard. Just shorthand.
Hope that helps.
