For moving stuff you can try MoveAnything
For actionbars, bartender is fairly popular and not particularly complicated.
As for unit frames and the like, a lot of people likes XPerl (my personal preference if I'm to use that is Perl Classic), Luna Unit frames is pretty solid too.
OmniCC gives a numeric cd countdown on your skills.
Personally I've found that which addons to use are more of a personal preference. Trial and error is the way to go, start with a few and expand your use if you feel like it.
I agree with oCB that is a very nice cast bar
also, when i had xperl on ED and joined group LuA errors would spam pop up
idk how to fix it
