I'm about 14 hours into both fixed and rotary wing. (14 each) It's much cheaper to get your fixed wing rating then get a helicopter add-on.
I would find a small airport with UNICOM to get started so you're not having to negotiate traffic and ATC right off the bat. Sign up for the ground school first and learn the basics. I went to ground school for years (completed it then went back for refreshers) and then started teaching part of the navigation section.
Believe it or not, the flying part gets kind of boring so you can kind of geek out on the nav part of it. As a bonus, you get lost less!
