Can anybody help me out and tell me the difference (if any) between an offset round bend hook and an O'Shaughnessy hook?

Does anyone prefer this type of hook (with the straighter shank and round bend) over the Extra Wide Gap? I had always fished the EWG's but had some problems with them this past summer (though it also had to do with wire size and line as well). I'd never put a lot of thought into my hook selection prior to that.

I know the lighter the line, the smaller the diameter of the hook generally. Anyother general characteristics to consider.

O'Shaughnessy hook

For a regular curltail like a 7" power worm I like to use the regular offest round bend worm hooks, I use these worms in thick grass and just like the thinner profile of the hook for that application.

For thicker bodied baits I like the wide gaps.

Thanks.  That is another general characteristic that should alway be considered is the thickness of the bait with regards to the gap.  

Is there any advantage by going with a straight shank hook as opposed to an offset shank?  I know a disadvantage with a straight shank is that the bait doesn't stay in place as easily  - but does it increase the hook %?

Not only are hook ups increased but with a straight shank hook you worm will slide up the line separating the weight from the hook which doesn't allow the bass to use the added weight to throw the hook.
