Personally I would also recommend the CWM wipe and flash (make sure you back up anything you need first and also wipe the cache, I've forgotten this step a few times before and ended up in a boot loop)

It will require you to root your device and install a custom recovery image onto it but that's not too hard to do and theres a ton of tutorials around the web for a variety of devices just make sure you search the model number found in settings>about device rather than the trade name such as galaxy s2 as different countries use different models so the files used to root and flash the recovery vary slightly.

You will find a lot of ROMs here: http://forum.xda-developers.com/galaxy-s...erivatives
Just read the thread to know if the ROM is good or not.
