I've been trying to install cyanogen.
Ok... first you have to make sure you have ClockworkMod recovery installed... it's the first thing in the list... if you don't have it and some things are greyed out you will need to touch that to get it installed.
Next... Go to Download Rom >> Cyanogen Mod >> Click CyanogenMod 5.0.7.1 >> wait for it to download >> you will see a gear thing in the notification area and if you swipe the notification area down you can see progress. When it's done downloading you touch it in the notification area and it will ask you if you want to backup your current mod and wipe data and cache... I recommend you check both and hit ok. The device will reboot into recovery, install the mod automatically and then reboot again back to the home screen.
Note: You won't see a huge difference in the theme... you have to install a theme if you want that... Below is an example of how to install Blue Energy (my personal choice)
1. Open ROM Manager and choose Download ROM.
2. Scroll down to “roberj13″ and tap.
3. Then choose the Blue Energy Theme option for Cyanogen.
4. When prompted, check the box for “App Pack for CM.”
5. Once finished downloading, you do not need to “wipe data and cache.”
6. Check the box to “backup” if you don’t have a recent one.
7. Press “OK” and your phone will reboot.
8. Let it work its installation magic, reboot and BAM! Done!

TIP: If you have apps installed now and you want to back them up you can install Astro File Manager... start it up... hit the menu key... select Tools... Backup... backup apps.
