I usually choose the projections I like the best, although they are pretty much all similar and about as accurate as a token card or crystal ball really are... just make sure you only use your league's scoring categories.
For the draft, I've done a few different styles over the years - but my favorite is sweet and simple. I just print out the tiers of players by position (usually on two sheets) and just player names and ranks, if you add stats you might as well print out a sheet per position and it starts to get confusing (in that case I would just update the CBS/Yahoo/ESPN rankings and use the PC only). But I like crossing guys off by pen, it's not too difficult and I get a nice view of how many players (in what tiers) are left at each position.
Also, if you print out sheets - you can mark who you like more, cross off guys you just don't like and won't draft (so you don't forget)... mark guys as injury risks, and underline your sleepers. If you want to add stats, maybe go with the longer paper so you can see homers/steals/etc if you absolutely need to see the stats (but less sheets the better).
In my roto league, the past few years I've kept track of all the teams rosters too - writing down and X'ing off a position as players are choosen... this way you see what position an owner needs that's drafting after you, but more importantly... if you can wait on a position. If you need a 1B and it's the 7th round let's say, and you've got your player all ready... but notice all the other teams have 1B drafted, you could pick another position and draft the 1B when it gets back to you. (same way if you like 3 players at 1B and only two owners after you need 1B, you can pick another position player and wait to pick the 3rd 1B you would settle for)
