Default Lenovo R400 Cpu questions

I have as above a Lenovo R400 and currently it has a really slow CPU. I wanted to buy an upgrade for it and have ideas of which to get but im not sure which of these would work best or if they would overheat my laptop. I found a support list and it does look like they are all on the list for being compatible, i just want to be extra careful before buying anything. my luck is i would buy the wrong one and mess up my laptop. so could you please tell me which of these would work best on my laptop?
1. Intel Core 2 Duo Mobile T9400, 2.53 GHz, FSB 1066 MHz, L2 6 MB
2. Intel Core 2 Duo Mobile T9900, 3.06 GHz, FSB 1066 MHz, L2 6 MB
3. Intel Core 2 Extreme Mobile QX9300, 2.53 GHz, FSB 1066 MHz, L2 12 MB
4. Intel Core 2 Extreme Mobile X9100, 3.06 GHz, FSB 1066 MHz, L2 6 MB

If you need anymore info let me know. I just dont know much about computers as you can probably already see. so i dont want to end up getting the wrong one. Thanks for the help in advance.

What do you currently have in the laptop?

Generally laptop CPU's are fairly spendy....so depends on how much you'd want to spend.

T9400 - $20 - $40 on eBay
T9900 - Average of around $95 on eBay
QX9300 - Average of around $140 on eBay

Probably the only one really worth the upgrade would be the QX9300 since you'd be going from a dual core to a quad core. If that's out of your budget too much, then the T9900 would be an "ok" alternative, but not much of an upgrade.
