Which 1st baseman and Shortstop should I pick up?

Helton is hitting .351 now. You don't have to wait for him to come out of a slump. Tejada over Alexei and Hardy who both are deep in slumps. Elvis is looking pretty good but he isn't as good as Tejada yet. Beside the fact that he is hitting 30 points lower. Helton and Tejada.
