Looks very good. Getting both LoDuca and Lieberthal was a great move; catching depth is extremely difficult to come by in league's this deep, and you also now have the option of shifting LoDuca to 1b if Durazo falters. Benson looks like a good pickup as well.
You do have quite a few question marks, but so will every other team in this format. The tricky part will be deciding when to bail on players who don't produce, especially with hardly any room on the bench. This will probably be a league won during the season rather than at the draft...
One thing missing from your mix is a reliever who might be bumped to the closer's spot. Williamson is nice, but gaining a second arm who can contribute saves would help.
