Season MVP would probably be Jose Reyes. That guy could flat carry a team in 2 or 3 categories.
Finals MVP is unquestionably Javier Vazquez - 3-0, 2.38era, 0.88whip, 13.10k/9 over the 2 week finals. Even Jim Thome's .360/12/6/8 line didn't match Vazquez's pure dominance.
Season LVP...hrm...there were so many. I overdrafted Anthony Reyes expecting great things and got nothing. Brad Lidge had a typical Lidge season on me. I'd probably have to go with a guy for whom I traded right after the draft though - Andruw Jones. Simply craptastic.
Finals LVP is tougher. I was quick to cut ties with anyone that was hurting my chances of winning. I'd probably give it to Pat Burrell due to my own mistakes. I cut Burrell to make a run at the sb category and during the time he was off my roster or on my bench he hit two hr's. His final line IN my lineup though was a disgusting 0.087/3/0/2 over an unfortunately large number of at bats.
