P100 questions... what do you think? Thanks for the help!

I know this isn't in the "What notebook should I buy" section, but I was hoping to get opinions mainly from you Toshiba people
First of all, I'm looking to replace my HP dv8000t, and I'd really like to get a Toshiba, but I have a few questions.
I think I'm considering this computer: http://www.toshibadirect.com/td/b2c/cdetland.to?seg=HHO&poid=327377&fgpn=PSPA0U-0F101R&src=ABEM&cm_mmc=CNET_Feed-_-Notebook_PCs-_-_-_-Satellite_P100_ST7211_Customizable
I chose this one, because I'm able to customize it to a certain extent, but I'm a bit confused when it comes to the memory, hard drive, bluetooth and wireless.
Here are my questions:
1. Are bluetooth and wireless integrated? Why does it mention something about an "antenna?"
2. Why is the 120GB 5400 rpm Hard Drive cheaper than the 100GB 7200rpm Hard Drive? If it's because it's faster, would it really make a difference if I went for the 120GB instead of the 100GB?
3. What is the best memory option they offer? If I see correctly, do they not offer at least 1GB RAM? In a review I read, it said something about being able to customize this computer with at least 3 or 4GB of RAM. How come I'm not seeing this? If you press "continue" it gives you the option of the 1GB memory, but does this mean I would have to install it myself? Would it come seperately?
4. What is the better screen that they offer?

Thanks so much for you're help and your time! I really really appreciate it!

Just to answer one of your questions; yes, a smaller capacity 7200rpm HD is going to be more expensive than a 5400rpm HD. In terms of how much difference it will make, it depends on what you plan on doing with it. If you play a lot of games that load from the HD regularly, or do a lot of Photoshop work (i.e. reading from a scratch file regularly, etc.), the faster HD will help.

Since you said you will be using a lot of Photoshop and doing a lot of video editing, which does involve a lot of reading and writing to the HD, the 7200rpm HD will definitely help.

The tradeoff is usually in additional heat generated and less battery life. A 5400rpm HD is still quite acceptable though, so you should probably be fine with that. Heck, some people even make do with the 4200rpm 200 gig HD in the P105. But for your needs, a 7200rpm HD makes sense.

 

Okay, thanks so much for your help.

I actually just figured out the answers to the other questions, so you guys don't need to post anymore. Thank you though.
