Hardware modifications to maximise battery life

i'm trying squeeze more life out of mbp, has lead me wondering hardware set maximise battery life. couple thoughts:

1) install ssd - best way go on , off usage, or green spinning drives better? also, having relatively full hard drive decrease battery life?

2) remove optical disk drive - use power in standby?

3) use single stick of ram - matter @ all?

4) underclock cpu think that's going far! on mac, if windows machine i'd consider it!
