Your pre and post workout shakes are gonna depend upon your diet and training scheduals. If you want to trim up, I wouldnt use too much dext/malto in your pre shake, perhaps 15-20g, and 20g of whey. Or if your diet calls for it, use none at all. This would put you in a fat burning state while you lift, but it will also directly effect the wieghts you can move.

A typical muscle building post workout shake would have 60-80g dext/malto (50/50 mix) and 40-60g whey. This will restore glycogen levels in the muscle, and begin the rebuilding process. But again this is diet specific.

Stay away from fructose all together. I believe its main purpose is to restore liver glycogen stores, and does not pass freely to muscle ... bad juju man.

For my money here are the suppliments I would use in order of importance:
Whey
dextrose/maltodextrin
fish oil

then a fat burner if you even need it (lipo6, ephedra caffien stack,syneburn)
