Carl I did several seaches for hooks and didn't find very much stuff. I have read alot of articals and books on bass fishing and alot of the Pro's have their own way of looking at it.
Me personally I have come up with my own system for hooks that has worked very good some of it has been from the books others is just my feelings on why I do it.
When I am just Texas Rigging a worm around docks and brush I use just a plain straight shanked hook (the one with the two little barbs at the top of it). The reason why is a feel I get a much better hook set with this type of hook. If you look at the hook you can see that the hook eye and the point of the hook are NOT in line with each other. This gives you a much better hook-up when the bass bites. Plus Larry Nixon said it was the best for Texas Rig. So that right there told me alot about why to use it. Another little seacret that I learned about the straight shank hook. If you tie it on with a snell knot your hook ups go up even more. If you look at the way a snell knot is tied it actually kicks the point of the hook out more when you set the hook.
Problems with this hook is the plastic baits want to slid down the hook more often. Little super glue fixes that problem.
Next hook I use is the standard off set round bend hook. I use this hook when Carolina Rigging thiner worms or centipeeds. The reason for this is because you are dragging the worm through rocks, weeds, brush, and so on. The off set hook keeps the bait up on the hook better when dragging it around objects. Also when I am TX rigging around really heavy cover.
To me I dont really like this hook because if you look at the line tie and the point of the hook they are in line with each other. When you set the hook on a fish I feel that the bend in the hook were the line tie is actually hits the fishs mouth before the point of the hook does. To demonstrate this tie on the hook and rig it with a plastic worm and then run the line between your fingers and slowly (please do this slowly so you dont hurt yourself "dont ask me how I know") pull the worm up to your fingers and see how hard it is to get the line tie and bend through your fingers! Then try it with the straigh shank hook. BIG DIFFERENCE. Think of your fingers as the bass mouth and he is clamped down on your worm. I would much rather get the straight shank hook through his mouth than the bend in the hook. Now do that with the straight shank hook tied on with a snell knot and see how it kicks the point of the hook out even more. Better hooks-ups are just going to be easier with this type of rigging.
You can bend the hook point out just a bit to help this but I hate to bend my hooks any because I dont want to make them weaker by bending them.
Extra wide gap hooks are used for really thick Plastic worms or tubes were you want a bigger bite hook to get through all that plastic. 10" power worm, big craw worms, soft jerkbaits and tubes are some of the plastics that I use the EWG hooks for. Again the line tie and bend in the hook get in the way of a good hookset. Try the finger method and see for yourself.
As far as sizes of hooks? I let the size of the worm tell me which size hook to use. If I am fishing a 4" skiny worm I dont want a 3/0 heavy wire hook because the hook is just way to big for that. A 1/0 thin wire hook would be better. 6" to 8" worms would be more the size for the the 3/0 hook, and so on.
Now saying that if you are fishing a weightless worm or senko type bait you want a bigger hook size to help sink the worm. Same with a soft jerkbait.
Size of the bass in the lake would be another consideration to make. I'm talking about heavy wire hook as opposed to thin wire hooks here. Thin wire will penitrate a bass mouth easier that a heavy wire hook. Will it be strong enough to land a trophy?
Sharpness of hooks. Always keep a diamond sharpner in the boat with you. You can find these at just about any retail store that carries fishing equipment. I always spend some time sharpening my hooks. After a couple of fish hit a time or two with the sharpener; it will make a differnce. Drag it across the back of your thumbnail. If it does not dig in soon as you start to drag, it sharpen it some more. This is the type sharpener I have fits right in my shirt pocket so its always there.

I hope that helps you some like I said these are just my thoughts on the subject and it works for me. Everyone does things a little different you just have to see what works for you.
Thanks for the question I think this should get some really good thoughts from the others.
