The 24-105 is quite a versatile lens for shooting indoors or even outside landscapes, it gives you a good bit of sub tele coverage.
Problem with selling it is, Canon made a boat load of then and there's now a version II so the original 24-105 USM lens, which is a L series lens with IS, is nowhere near worth what you may have paid for it new.
Keep it and learn how to use it.
I can understand your conundrum. I have a 24-70mm which I use all the time, but it's on my full frame camera. Unfortunately, you lose out on the wider end of the focal length since it's on a dx camera. No, it's not great for birding or wildlife, but I didn't take it off my D800 on a vacation trip to Santa Fe and Taos, and I had my 70-200mm and 28-300 with me as well. Since you're not going to go full frame (and I don't know if this is a full frame lens, anyway) I would suggest selling the lens if you can get something for it. I'd suggest picking up something like an 18-105 if something like that exists. Save up for the 100-400L VRII for distance, birding, and wildlife.
