I upgraded my MacBook6,1 MC207LL/A system which has the 2.26 GHz P7550 and the MB61.00C8.B00 boot ROM today with 2x4GB 1333MHz (Corsair CMSO8GX3M2A1333C9) and it is indicating the RAM is 1333 MHz and I haven't encountered any issues yet. Update: Although the system was stable, it did seem to be running quite hot. I didn't spend enough time using it before upgrading the RAM to know if this was due to the RAM or not. I went ahead anyway and underclocked the RAM to 1066 MHz by modifying the SPD of one of the sticks using i2cdump and i2cset in an Ubuntu install on a USB stick.
The 2000 and 2001 Camry models take 9006 (HB4) bulbs for the low beams and 9005 (HB3) bulbs for the high beams, rather than the 9003 (HB2) linked here -- at least for the North American models I've looked up.
If you have the original owner's manual that came with the car, there's a table of all the bulb types you'll need for different lights in the "Do-It-Yourself Maintenance" section. It doesn't hurt to double check.
