Are you planning on racing it?
I've been down this road before. I had 2.73's for a long time in mine. I would go with a converter first. You will pick up more with a converter and still get good mpg with the 2.73's. Despite what some will tell you....2.73's are plenty capable with a good converter. I ran 11's with stock LS1 and 2.73's....getting close to 30mpg on the highway.
My other suggestion if you plan on racing is to find a complete 3.42 rear. A lot of times that's cheaper than a gear swap. When you add up gears, install kit, labor it gets pretty pricey. You will also have that 2.73 rear as a spare. I had to go back to my spare twice.
I've had 2.73's, 3.42's, and 3.73's behind my 4l60e. Big difference from 2.73-3.42. Not much from 3.42-3.73 especially if you plan on getting a converter.
A little more info for you with the swap. Because you have 2.73's you will need gears for a 2 series carrier. So...pull out (stock) 3.42's are out. 4.10's are also out. Here are some prices if you haven't looked it up yet.

I hope I'm not insulting you or anything. I'm not sure how much you've messed with this stuff. Just giving you my experience with it. If I can help with anything (including wrenching) let me know.
