Just added this in the first post:

Note: /sdcard/bolt_scripts will need to be copied manually from the main CWM zip. There is a bug in CWM5 that sdcard can't be mounted correctly. Not sure why.

It will affect your phone's performance (making it faster, less battery draining) if you don't do the last step (remount/sqlite_optimize)
Check BetterBatteryStats (a free app in XDA) to see what was draining. Do this before you charge your phone fully so that the stats don't get deleted.
Ahh, right. I saw Touch Move from tegrak and I'm studying Siyah's sources to understand more about the touchscreen tweaks that Siyah implemented.

iori's instruction is the simple version of it. Let me know which line you're getting stuck at
It's ok. sqlite_optimize will increase performance and save disk space, but the effect is minimal (like ~1-2% more of performance).
Weird, it might be your frequency getting stuck at a certain frequency instead? Check CPUSpy?
Your wifi scan interval is too high? No, ThunderBolt! doesn't fix that.
