Salary Leagues aren't as easy as I thought they'd be!!!!

[BigBlue]

So I joined my first salary league this year. I took over for a dead team and inherited keepers of: Chipper Jones, Jorge Cantu, Clint Barmes, Bartolo Colon and Rich Harden. At the ned of the draft I was left with this:

C- V-Mart $20
1B- Helton $15
2B- Cantu $1
SS- Barmes $1
3B- C. Jones $9
LF- Berkman $21
CF- Beltran $31
RF- B. Giles $6
UT- Sheffield $23

SP- Sheets $30
SP- Escobar $7
SP- Cain $14
SP- Mulder $11
RP- Benitez $6
RP- Turnbow $16
RP- Jenks $16

B- Vazquez $5
B- D. Cabrera $5
B- Ordonez $4
B- Mora $5
B- Shelton $4
B- C. Guillen $2

$252// $260

What shouldn't I have spent soooo much money on if anything? Where should I look to improve?
