Ok, sorry in advance for the paranoid line of questioning but whenever I do this I feel like I'm defusing a bomb lol. Done it tons of times with my OV and now the Marquee, but the Marquee is different. I've killed my Marquee updating the prl on CT and brought it back to life(on the third day if you must know)using the guides here in these forums. So I've had an emotional time so far with the Marquee, but I love it.
Sorry I often drift.....
just double checking my steps as some had bootloops early on.
1)Make a nandroid backup(done!)
2)Download necessary zip files(Rom1b, gapps)
3)Boot into CWM, wipe data, clear cache, dalvik cache
4)Flash alpha1b,(wipe or clear here?), flash gapps
5)Reboot
Hope I'm not missing any flashing, wiping or clearing
