here is my info:

Full Charge Capacity (mAh): 4536
Health Information:
Cycle Count: 404

Let me know if this is bad, particularly the "-1044 amperage"

Battery conditions
The battery condition tells you whether your battery is functioning normally and approximately how much charge it can hold.

Here are the possible conditions:

Normal: The battery is functioning normally.
Replace Soon: The battery is functioning normally but holds less charge than it did when it was new.
Replace Now: The battery is functioning normally but holds significantly less charge than it did when it was new. You can continue to use the battery until you replace it without harming your computer.
Service Battery: The battery isn’t functioning normally, and you may or may not notice a change in its behavior or the amount of charge it holds. Have your computer checked by an Apple Authorized Service Provider (AASP). You can continue to use your battery before it’s checked without harming your computer.

You don't have to change it!
The - amperage is just the current energy consumption of your laptop.

Now, the reason I had the text is because my battery also wants to be serviced since a few weeks. In my case, the problem is that the battery does estimate it's remaining charge wrong. Calibrating didn't help. About a month ago it had 80% of it's original capacity, which I thought was pretty good for a 3.5 years old battery. Now it's down to below 70%, but the problem is that it actually has only about 50% left. On a few occasions the laptop would shutdown although it showed 40 minutes left. And that's the hard shutdown, not the one where it goes to sleep and restores everything after you reconnect it.

TL;DR:
If you have to rely on your battery, I would get it exchanged. If you mostly work near a charger, you don't have to do anything. It won't explode.

I hadn't used my 2007 MBP in a while. It already had a new battery at some point, but the dormancy appears to have left my battery in this 'service' state.

It's actually working alright and for a while after calibrating the service message disappeared. Then one night I was using it and the remaining battery just plummeted and then the laptop cut out. Ever since I've got the service battery warning again, but it's also reporting the time left a little more realistically at about 2 hours.

Basically it seems to mean that power delivery is unstable. For use around the house it's fine and I won't be changing my battery, but if this was a machine I needed to take out and about I'd be looking for a new one.

I'm on it now, probably been on battery for about 45 minutes, and it's saying 81% and 3h11 remaining. There's no way that's right... it was saying 2h when I took it off charge and that's far more in line with what I'm actually getting.

You might try resetting the SMC, then re-calibrating using the procedure outlined in the following link. This should answer most, if not all, of your battery questions:

Ok, I will give it a try. I don't expect the battery to improve, but it should at least give me a better estimate of the remaining time, not shutdown without warning. Thanks.
