7200 rpm vs. 5400 rpm

OK, so I may skip dual core and get a high powered dell 630m. I have a few questions. Supposedly its 9 cell battery can pack nearly 6 hours of battery life. Thats outstanding. Now if I spent the money to get the 7200 rpm HD, would it be a huge difference? Also, how much battery life would it take from me? Obviously it uses more power since it is spinning more... Also, my processor choices are the following:

Intel® Pentium® M Processor 770 (2.13GHz/2MB Cache/533MHz FSB) [add $500 or $13/month2]

Save $100 Intel® Pentium® M Processor 770 (2.13GHz/2MB Cache/533M [add $400 or $10/month2]

Intel® Pentium® M Processor 760 (2GHz/2MB Cache/533MHz FSB) [add $300 or $8/month2]

Save $100 Intel® Pentium® M Processor 760 (2GHz/2MB Cache/533MHz [add $200 or $5/month2]

Intel ® Pentium® M Processor 750 (1.86GHz/2MB Cache/533MHz FSB) [add $100 or $2/month2]

Save $100 Intel ® Pentium® M Processor 750 (1.86GHz/2MB Cache/533 [Included in Price]

Intel® Pentium® M Processor 740 (1.73GHz/2MB Cache/533MHz FSB) add $0

Which should I chose? Budget is not the biggest issue but I dont want to get the 770 if it isnt necessary. Thanks guys

EDIT: does the 9 cell battery add SIZE to the laptop. I am not too worried about adding 5% weight. But does it extend out at all?

EDIT: Google told me that it does extend out. Does anyone think I should go with an HP DV1000 instead? Dell looks like the processors and ram and hard drive are more advanced. I really dont know what to do. This is killing me

On the choice of processor, IMO I would just stay with the one you have and put the money toward RAM or something. If you look at the percentage increase in power and capability of the chip, you're not gaining all that much, at least not anything worth $200 to me. If I was in your situation, I'd save the $200 and put it toward something that will be a better use of your money like a larger HD, more RAM, better video card, something like that.
 
7200 will generate more heat and use more battery. A lot more? it all depends on the HD, but usually not that much. As for speed difference, an average user won't even notice the difference between the two. The only way you might see a difference is when you're working with large files such as giant Photoshop files or transfering large amounts of data. Now, the 7200rpm speed is just a max number, your HD won't be hitting that number at all times. It will hit when transfering large files, of course.
