Yay for more steampunk! I'm in the middle of writing one now, but it won't be done for a bit.

Can't wait to see what people rec :)

I've recced this fic here a lot, but I'm going ot keep doing so whenever it's relevant :-P

Holy Clockwork Angels (http://ghostrunner.dreamwidth.org/1678.html) is a steampunk AU. It's Jo/Ruby and has a neat plot with mystery and action and such.

If you don't mind it being slavefic rather than a free servant, I'd strongly recommend poisontaster's A Kept Boy. Jensen is JDM's slave who is determined to be a GOOD slave despite his new, abolitionist master's odd ways. (This does not do justice to the complexity of the story but at least gives you a slight hint of the setup.)

This might fit your request for #1 :)

Very awesome steampunk:

Apophenia Lux (http://apophenia-lux.livejournal.com/)
When Sam's girlfriend Jessica goes missing, he decides to leave school and enlist the aid of his brother he hasn't seen in four years. Largely an excuse to stick the boys on Mars, and give Dean an airship.
This is such an amazing piece of work, written with so much creativity and fun and ... and... heck, go read it!
