Tough question with a lot of variables but Gordon at 14 dollars already seems pretty expensive. Willingham seems like a decent price but I also assume his level of production could be easy to find in even cheaper players. I like the signing of Doumit. Hard to find catchers that can do what he did this season in average and pop. I'd invest in the cheaper McCutchen before Rasmus right now. Rasmus has been a bit disappointing and his route to the bigs isn't as clear as McCutchens. I think I'd pay the price on Votto because his power and great average already are a very good sign. Trust him before unproven prospects as we all know baseball (Gordon) is extremely hard for prospect projections.
Finally, you always have to look to consolidate that talent, so if you can, do it! If you can find IF help that way, you'd be good to go.
Not sure how much that helped, but it is a start I think!
