I read through this entire thread and there are many questions that keep getting asked over and over. I asked gomorrah to post a FAQ since he has the first post after the OP and he asked me to write one up and he would post it. my question is;
what questions and answers have people seen again and again?
So far I have:
Visual Voicemail: Flash into sense, backup with titanium, flash back into CM7, restore data. Or use Google Voice or Youmail
WiFi Sleep Policy: Change WiFi sleep policy to never, menu>wireless and networks>WiFi settings>menu>advanced>WiFi sleep policy. Honestly it's been so long since I've done this I'm not quite sure what it fixes but I know it's been mentioned quite a bit. I do know that this will significantly improve your battery life also with some ROMs changing the WiFi sleep policy setting to never sleep can prevent random reboots.
Camera Shutter Sound: To remove shutter sound you need to remove shutter.ogg in system>media>audio>ui. Remove it through Root Explorer, ES File Explorer, ADB, etc
GPS fix: Flash into a sense rom, download MSL reader from the market, input ##GPSCLRX# into the dialer, reboot, reflash into CM7
Facebook Contacts that fail to Sync: First go into the Facebook app and select settings>sync contacts>sync all, then go into sync and sync now. Now go into your contacts list and select a contact the press menu>edit contact>menu>join, you should see all your facebook contacts in there and you can join them to your phone contacts. After that you can go back into the facebook app and switch back to sync with existing contacts.
Google Apps: For apps such as market, gmail, etc. you have to download and flash the latest gapps after flashing the rom, it can be found here

Does the camcorder app support 720p video recording?: As far as I know not yet, but they are working on it.
HDMI: Working for the most part, not integrated into the rom yet. Should be in there by CM7 final.
How can I get the swype? : Go to Swype.com and sign up for the beta, it's really simple to download and install from there.

SD card speed issues, I'm not sure if this has been fixed in newer releases yet
The issue is
SD card speed over USB mount, use the "USB-MS" option in Amon_RA recovery to mount your SD card. That has not been addressed in RC2 or any of the nightlies so far yet. Thanks aph. There is a know issue that has been logged (#3067) by the CM team about the SD card becomming "Damaged" during RC2 install. This affects a small number of phones with a possible work around of a second reboot after the install. Thanks to s2kdriver
My power and control widgets in the system tray disappeared. Changing themes can cause this problem. Open Rom Manager, fix permissions, reboot.
For those having a
jittery video in the YouTube app, go into settings and select HQ video and that will fix it. Fix posted by JAYDIG, I did it and confirmed it works.
Laggy screen transitions and general performance? download osmonitor (from the market) and see what heap size is being requested. Turned out ADW wants 38M and by default the heap was set to 32M. Get VMheap tool (also on market) to adjust to 40M. No more problems with hesitation or lagginess, and I think it helped battery life some too. Thanks to nc_carol
There are a lot of kernel questions. There is a stock kernel included in the rom (a rom won't work without one). There are alternate kernels available, if you have issues and are using an alternate kernel, post those questions in the associated thread.
This is what I have so far. I'm not foolish enough to believe that after posting this there won't still be people that post questions without bothering to look anywhere for the answer but my hope is that it might help to answer some questions and reduce the number of repeat questions.
