You should go for the fastest stuff but look at the price jump like the processor for example

Intel® Core™ 2 Duo processor T7200 (4MB Cache/2.00GHz/667MHz FSB) [add $225 or $7/month1]
Intel® Core™ 2 Duo processor T7400 (4MB Cache/2.16GHz/667MHz FSB) [add $400 or $12/month1]

the only difference here is .16ghz and for an extra 175$ its definatly not worth it. What I would go with here would be:

Intel® Core™ 2 Duo processor T7200 (4MB Cache/2.00GHz/667MHz FSB) [add $225 or $7/month1]
Genuine Windows® XP Professional with re-installation CD [add $159 or $5/month1]
1GB Shared Dual Channel DDR2 SDRAM at 533MHz, 2 Dimm [add $65 or $2/month1]
100GB 7200rpm SATA Hard Drive [add $175 or $5/month1]
256MB NVIDIA® GeForce™Go 7300 TurboCache [add $129 or $4/month1]

This is what "I" reccomend, now if you budget doesnt allow it then get what you can afford.
