As a bonus question, since if I need to go with the T60P it will have to be a second hand unit because of price.
Hope to get some help

I have a Z61p (1920x1200 WUXGA LG Phillips) and a T60P (1600x1200 UXGA Hydis). I do think the Hydis looks better, but not significantly (mostly it is just a brighter screen). As far as the smallness of text, that really is a personal thing. I don't have perfect vision, but I like the WUXGA over the WSXGA. Mostly, this is because I do a lot of programming and research and want to have multiple windows open side by side with out scrolling left/right to see their contents.
As far as the difference between the CPUs go, most hardware review sites stated there is about a 10% difference in performance between a CoreDuo and a Core2Duo. Which should mean that a 2.16Ghz CoreDuo will perform similarly to a 2.0Ghz Core2Duo. However, there are two other reasons the Core2Duo might be still perferable - the Core2Duo at 2.0Ghz should have a lower power consumption then the 2.16 CoreDuo. And the bigger reason in my mind is that the Core2Duo has the 64bit instruction set. Now, this is not really an issue if you don't run a 64bit operating system (ex. Linux x86_64 or Windows XP/Vista 64bit).
The final question, I don't play a lot of games on either laptops (they both have V5200s FireGL), But, I have loaded SimCity4 and Civilization 4. They both seem to run fine. Also, the FireGL card is evidently a X1600 with specialized drivers. You can download Omega drivers which will allow your FireGL to be treated as a X1600. I have not tried this, so I don't know what performance gain there is.
