I agree with allday in that you do not want to put to many players in your do not draft.
If you do not want Santana in rd 1 just put enough hitters ahead of him so you don't get him. ie if you draft 11 just put 11 bats above him. If you keep getting him in rd 2 just do the same up until you have drafted in rd 2. Now this is tough when you do not know what your draft order is until 30 min before your draft (some like that setup but I would not participate in a league that drafts like that).
3-ranking and drafting is the best thing about fantasy sports. you need to want to put in the time to enjoy the sport.
4-most people likely will not share their rankings because they do put in the time and time is valueable. But a few have posted their rankings here just do a search and a couple will come up. Also look at the mocks here that are posted in the rankings and that will give you a good ranking.
5-yes that does favor hitting over pitching
here is a fun free site that someone posted earlier. It is fun to play around with.http://www.lastplayerpicked.com/priceguide/
you are not an auction so just put in $0 when you are asked your total budget and min bid. Than you put in your 8 hitting stats and 5 pitching stats and you will get a value for batters & p's. Now it doesn't put them together so you will need to merge them and than set your Yahoo to the merged results if you choose.
