Now the wobble is enough to just fit within the boundaries of my front derailleur. The chain sometimes rubs against the edges of the cage depending on what gear I'm in. It doesn't look like I bent the frame, but I'm wondering if it's okay to run it like that, and if so for how long. Should I replace the crank or can I just get away with replacing the outer ring? I commute on the bike 14 miles round trip every day. My bike is a 2010 Surly Long Haul Trucker with what I believe is an Andel RSC6, 26/36/48t. Thanks.

You may need to replace the chainring but you can also try to straighten it. Find where the wobble is and then use an adjustable wrench to straighten out the bend. Get as much bite as you can on the ring with the wrench and bend it is small amounts until it's as straight as you want it to be. At worst, you can't fix it and will have to replace the ring. At best, you'll have a great mechanical story to tell.
