Sounds like you've been getting all the same ideas I got, and give out. A couple other things you might also do, have a set of clothes already at work to change into, that way you aren't wearing your riding gear all day and then riding home in it. Hopefully you can let it dry out before riding home.
I have the fortune of a back room to hang stuff up, and keep a towel and four changes of clothes. I don't have a shower so I keep a bottle of cologne and deoderant at work to freshen up at work, after a sink bath.
