ASUS P5E Q9300

Have some questions that some of you may be able to help me with my new build...parts should be here Friday from Newegg. I've done as much research as I possibly can but have questions.

I ordered the ASUS P5E, Q9300, Corsair Dominator 4Gb(2x2) DDR2-1066, and EVGA 8800GTS 512mb 256 GDDR3 PCI-E 2.0 video card.

My main concerns are:

1. Will the mb work out of the box w/Q9300 or will I have to update the bios first? And if so how do I get into the bios if the mb doesn't recognize the processor? I won't know what version the bios is until I get the mb.

2. I also need to know if the 2-Corsair Dominator 1066 2Gb chips will work together on this board. I read in the manual(online) that this board won't work with 128Mb chips. I don't really know if these chips are 128 or not.

3. I don't have any concerns about the video card...other that overheating. Should I pull the stock fan off and go with a Zalman like I did on my ASUS Silent 8600GT. The 8600 ran at almost 180 F. After putting the Zalman on...it dropped the temp by 70degs.

4. I have a Zalman 9700led CPU cooler...so no worries there!

5. I'm using XP Pro 32bit only because I don't have a copy of XP Pro 64 and know I will only see 3.25Gb...anyone have a copy?

If anyone has a similar system and situation out there...I'd appreciate any troubleshooting advise before I get into this mess!!
Thanks....you guys "ROCK"
