Revisions in Oblivion

So I'm working on the last my of revisions for Hide and Snake Murder: Book 2 in the Shay O'Hanlon Caper series. As I'm going along, I come across simple things that I think I will remember from one book to the next, but of course I don't. Things like Boxer or boxer (when it comes to referring to dogs), or AM or A.M. or am?

I did get a style sheet for my first book, but now that I'm cranking away on revisions for the second bbook, do you think I can find it? Of course not. Then a light bulb popped on and I figured I could look in my first book and see how things were done. However, I'm not at home, and don't have a copy with me. So it was a good idea that fizzled fast. Of course, I tried to check the site given to me by my poor, put-upon (by me) editor Nicole (http://www.onelook.com/) but 29 citations came up--both capped and uncapped. So I decided I'll do my best and let Nicole have at it, although I do try and do whatever I can to make it easier for her, and do it right the first time--if possible.

I do have a copy of The Elements of Style, but that doesn't always cover the things I have questions about, especially for subjective stuff that varies from one publishing house to the next. So how do the rest of you keep track of those pesky revision rules...which way this or that is supposed to go, what's capped and what's not, and all the rest of it?
