I am on the same page as you just need a little help to start up.
From what I have gathered Scrypt mining is the way to go
This is the link I have going to be using hope this points you in the right direction:
http://www.cryptobadger.com/build-your-own-litecoin-mining-rig/also I believe for mining alt coins you want to join a pool which changes to the most profitable coin of the automatically.
Sorry couldnt be much help but in the same boat as you.
