questions about proposed rig

I would love to get answers to these questions before I buy.  I will call DS sales, but in case anyone has a comment on any of these topics, I thought I would post here.

Here's my proposed rig:

http://www.digitalstormonline.com/comploadsaved.asp?id=108106

basically a Q6600 cpu, 2GB 1066Mhz memory, and a 8800GT 512MB video card.

How I use the computer: I don't play first person shooters - I like strategic games like Starcraft.   I also wnat to do music composition using Sibelius, and some web programming.  I'm upgrading my 5-year-old Dell because I want a faster system and I need a video card that will support higher resolutions for my new 22" Samsung.

1) After reading several articles here, I don't think I should have this system overclocked, and here's why.
a) I understand that the 1066Mhz memory is already overclocked - it's handpicked 800Mhz memory that survived OC testing.
b) with no memory overclocking, the memory speed is 1:1 with the FSB of the Q6600.  Overclocking the FSB will not result in the proportional speed increase, at least I don't think it will from my reading.
c) it will take DS longer to deliver :)

2) with no overclocking, should I bother to invest in Stage 2 cooling?  I also have the two mirrored 320GB disks and two DVD drives.

3) when I order 2 GB memory, is it installed as two 1 GB sticks?  I just want to be sure that if ever decide to go with 64-bit Vista that there are enough slots for me to add more memory.  I want 32-bit Vista right now because I still run some old apps that I suspect are 16-bit.  I realize that 32-bit Vista can't address 4GB of memory.

4) is there any reason to buy a more expensive motherboard with this configuration?  Any reason to buy a bigger power supply?

5) does Vista Home Premium come with MS Word?  XP came with MS Word, but the web gives conflicting answers to this question.  Most people say no, but one person says "yes, but you have to do a windows SEARCH for it".  Any definitive answer?  I spent 15 minutes hunting around the Microsoft site with no luck.  I need Word and don't want to buy it if I can avoid it.

6) My wife will keep her old XP computer and will want to print to a shared HP printer connected to my new rig.  I read a few horror stories about problems networking XP to Vista, but they may be old news - I hope (?)

7) Re: video cards... this guy: http://forums.nvidia.com/index.php?showtopic=55181 suggests that the 8800 GT is newer, faster, cheaper than the 8800 GTS. 
Maybe he is wrong (?) and of course he is talking about the 320MB model, but I am wondering why anyone would pay $100 extra for the 8800 GTS unless they already had one and were upgrading to a dual video card configuration.  This review http://xtreview.com/review219.htm also suggests the GT 512MB is better than the GTS 620MB.

8) sound card - I wear a cheap monaural headset when gaming so I won't disturb my wife.  Any reason I should get a more expensive sound card?  Only reason I can think of is to get midi ports, but I just ordered a midi/usb cable so I may not even need those.  It would also be nice to get good simulation of classical instruments, but the web was no help there.

THANKS!

Thanks Sky - that was very helpful.  I was surprised at your answer to the first question about the FSB and memory.  I will do a bit more reading.

1. It really doesn't matter. It's just a matter of opinion.

2. Stock cooling should be able to handle it.

I found a very helpful article about the relationship between the FSB and memory:

Scroll down a few posts to the long post by Prototyped on Oct 9 2007.  Terrific post.  To sum up:

The FSB and memory don't need to be in perfect sync for optimum performance with today's Intel processors.  The main thing is: the memory should be not be slower than the FSB or a bottleneck is created and you have wasted money on the processor.  If memory is faster than the FSB, some performance improvement is still seen because of reduced latency.

It's still confusing.  A lot of factors contribute to performance, and the best decision also depends on how the user will be using the cpu, and whether they plan to upgrade individual components or buy a whole new cpu down the line.

So for my system, I can save a few bucks by switching down to 800 Mhz memory and getting my Q6600 overclocked.  This is what I will suggest to the salesperson.
