If you're looking at the weapon in the inventory, there will be an option to "Recharge" the weapon if you have filled soul gems. I didn't realise I could do that for ages but now I use enchanted weapons (and keep a big stash of soul gems) all the time. If you're using a 360 controller, the button to recharge is RB.
And if you're on the PC (like you should be), it's T.
If you ever need soul gems, get into the College of Winterhold. One round trip through the mages in there and you'll have 5 filled grand soul gems and an empty black soul gem (which is stupid easy to fill with a grand soul: just take the soul from a bandit or other human). I don't even bother with any soul below grand.
Try getting hold of Azura's Star as well if you want a soul gem which is reusable. Best advice is to do it early in the game or you'll end up facing some very strong Dremora which will take you apart in seconds. I only managed the quest by using the "Become Ethereal" shout. Depending on how you complete the quest you can get a version of the star which can absorb souls from humans (nice and easy to get grand souls) or a standard version and access to a powerful mage companion (Aranea).
I just found out that the magic cost reduction works for weapons, too; if you have a weapon that does shock damage and you're wearing 100% reduced destruction magic cost, for example, the weapon's charge will never decrease.
I think it was already mentioned but followers are currently bugged. They level up with you but their skills do not. If your follower seems weak, do this:
Remove all items you want your follower to keep Get follower to leave your service (wait until it says it at the top of the screen) Enter console Click on follower Type "getavinfo health", or any other character stat. #this should return two values - a "current" and a "base reference". Bethesda have got the two values the wrong way around for follower levelling purposes. This way you can see what the correct stat should be (the base reference). Type disable Type enable Exit console Wait for follower to reappear and do the "getavinfo" test again. Everything should be normal.
Using this method Lydia changed from being one-shotted by Falmer to being able to take on Whiterun's town guard single-handed.
Quick questions - does gear cost reduction for spells etc effect staves? And, if so, does the Staff of Magnus count as destruction or "special" or somesuch?
Show them your butt, and when you do, slap it so it creates a sound akin to a chorus of screaming spider monkeys flogging a chime with cacti. Only then can you find your destiny at the tip of the shaft.

What does Staff of Magnus do again? Absorption? Absorption and draining fall under destruction.
The damage is pretty pathetic at high level due to the scaling but it's a good way to get rid of puppies that keep nibbling. I just threw it onto my wench so she stays out of the way of my warhammer which would surely 1shot her. It's good to know that my theory was correct, now I just need to make her a cost reduction set for permazappy. She also has that dragon priest firestaff that makes HDR flip the christ out so randomly my screen goes pure black from the fire.
