I pretty noob-ish as well compared to most on here. But I also would recommend rehydrating. I brew almost all my beers with the 05 and I rehydrate. The basic consensus is that rehydrating ensures you get most all of the 230 billion cells in each pack. I have read more than once that you can expect about half of that when pitching it dry.
Plus, after you do it once or twice, it's really no more work than pitching dry. I actually just use tap water at 75-80 degrees into a sanitized container with sanitized lid. I know my water must not be too nasty because I never used to boil my water for top offs when I brewed with a smaller kettle.
A good and healthy fermentation with little to know lag time can only be a good thing, right?
