1st H2H team - could use some suggestions, esp. on pitching

[Egregious]

Hi, Here's the team I just got in an autopick draft in a yahoo public league. It's my first head-to-head team (as I mentioned in a post over in the Fantasy Baseball Talk forum), so I'm not sure yet if I should go about constructing a team differently than for roto.
My plan is to try to pick up another closer or likely closer, and some other good middle relievers to fill out pitching, and then go with WW pickups (2 start weeks, etc) for starters beyond Pedro and Harden. Does this sound reasonable?
Any other suggestions on how I might improve my pitching would be very welcome. I'm pretty happy with the offense I ended up with, I'll be grateful for any suggestions there, too.

Pitching looks really good. Your offense scares me though. There is a lot of injury prone/young players there.

yeah, I take your point regarding the offense. I kind of misguessed how other people would draft. I'm feeling pretty good about these young guys, though - I think they'll surprise a lot of people this year.
