bike savagely beaten with bent eyelet for rear derailleur.
i beleive someone was trying to steal my bike or some drunk college kid attacked it so heres my question. the eyelet that the rear derailleur hangs off of is bent inward really badly and i have tried a few things to fix it but its not really working. would my best bet be to take it to a LBS and have them work it out?
Im riding a surly crosscheck
Pics of the carnage( the second one is the real problem i already know im going to have to buy a new rear wheel):
EDIT: wont let me post pics so heres the links

I bent the derailleur hanger on my Cross Check and the LBS fixed it for a nominal charge. It's apparently pretty easy if you have the tool.

Put an allen wrench into the rear deraileur and pry it back out, close enough to ride back home. Any bike shop should have the tool to realign the hanger, or if it has a replaceable hanger then you will need to probably order one unless you have a surly dealer near by. The hanger needs to be straight in order to tell what condition the rear deraileur is in also.

That really sucks! I'm curious which type of lock you were using and how your bike was locked up. Does it appear the damage was done by someone trying to pry the lock open?

that is awfull where do you live? you may need to find a better place for you bike, put it where the is a bit more visablity.
I doubt there was a theft attempt kids, drunk ones, just do this for the fun of it. I saw a few of these when I worked in Boston.
that hanger does not look too bad, the wheel took the brunt of the beating. as stated above a good shop and knowledgable mechanic should be able to strighten this. have then check the dropout, and frame alignment too.

As others said, the hanger needs to be truly straight. The job is straight forward but requires a tool or gauge, which costs $40-50, vs. probably $10 to have it done at a shop. It's your call whether to buy the tool or pay someone to straighten it.

I had a Hard Rock with a bent hanger and took it to the LBS to have the derailleur replaced and the hanger straightened. They replaced the derailleur and did something with the hanger, but it still wasn't shifting right. After fighting with the derailleur I noticed that the hanger still wasn't straight. I got out the big adjustable and fit it to the hanger tightly. This gave me excellent leverage to bring the hanger in line.
If you try this, check the progress with a flat edge.

Someone kicked your rear wheel in. Jackasses do this all the time in my town. You should avoid locking your bike up in high foot-traffic areas if possible, and in between other bikes would be good too. Have the LBS straighten the hanger with a derailleur hanger straightener because if it isn't plumb within a couple degrees an idexed shifter will never shift properly.

Take it to a bike shop and don't try to do it yourself unless you got a Masters degree from MAcGyver University. You really need the hanger to be as close to vertical as possible for optimal shifting. Eyeballing it won't cut it. They have a special tool for this.

Not sure the rim is fixable, that's a lot of tacoing there. They will want to have the wheel trued up, or replaced to align the hanger. The shop could throw in a spare wheel for the alignment if you are doing something different with the wheel. (The tool uses the wheel itself for measuring the alignment.)
I would love to catch some asshat doing that to my bike... it would be a VERY ugly scene. Good luck!

sorry to hear that. I had a similar problem after my bike hit the pavement hard and damaged the derailleur and derailleur hanger. I had take it the LBS and had replace both hanger and derrailluer. It's sucked...but glad the frame was ok. Unfortunately, with surly's, the hanger is a part of the frame. It's steel so it should be easily straitened. Best option probably is to take it to the LBS and have the pros work on it. Good luck.
Here's a pics of my bike after the accident:
