Thanks guys, I'll start working on the replacement. Info on the battery replacement and subsequent alternator delete will be documented here:

On the commute in, I got a very nice 63.8 mpg in this morning. I was pretty happy with that. It was a bit warmer out which I'm sure helped. Still got nailed at a light or two though, so I know I could have easily had a 65+ commute in the same weather (~40F).
