To start...
When buying lumber, you should always look down the length to make sure it isn't warped / twisted too bad.
When you get the lumber at home, ALWAYS crown every piece and mark them accordingly. Make sure your 'C' is always facing the inside of the room.
Your top and bottom plates should always be your straightest pieces. FYI -- Bottom plate should be PT 2x4 or regular 2x4 with sill foam underneath.
Thats what I followed when I started framing my basement...
