~$2,000 System Build Feedback

Hi all. I'd like some feedback about this potential build. I've carefully read Tom's reviews and the feedback from Newegg, and have picked this list of parts for my future computer:

Here's some specific help I'd like from the community here:

1) Is there a cheaper/better monitor I can get? I want a hi-def experience with no less than 23".

2) Are there any obvious flaws or shortcomings?

3) Can I get this shipped from another website cheaper? I live in Hawaii and S&H can be a real ripoff.

4) Also, on that note, my home is very hot! I live on a tropical island with no refrigerated air. Obviously cooling this computer will be very important - but I don't have the budget for an expensive liquid cooling system (nor do I like the idea).

5) Is there a sound card anyone can recommend? Though I'd prefer not to spend too much more...

And finally, this computer will live a balanced life. I use my computer for a lot more than gaming. I use my computer for studying, spreadsheets, web browsing, and music half the time. The other half will be spent playing World of Warcraft and Starcraft (and surely other games as they come along).

Thanks for the help!
