They improve your phone signal, bluetooth, wifi and gps inproving the quality and purhapse battery life (in theory)
2)how to create a full backup of your current phone/rom/state and be able to recover it anytime later if you wish...
once you have a custom recovery installed (Clockwork Mod or Amon_Ra) you can do a nandroid backup which is a complete system image that can be restored at a later date.
This is two of the initial concerns that Noobs like me need to know to, Thanks..
