Windows Phone Development: Questions about getting started

Any WP8 Devs out there?

Previously I've been involved with dev teams for iOS, Android and also contracted-out WP7 development before but strictly from a 'high-level app design, outline what it needs to do then nitpick during testing' type (or if you want to put it another way, the guy who's paying for it all).

I've bugged out of most of that as a business in the meanwhile, but I'd like to tie up some minor loose ends for me personally in WP8 and I'd like to know if I can do it myself.

What would you recommend to someone who wants to fast track learning WP8 development?

a) I'm not hugely resource-limited. Obviously there's a benefit vs expenditure aspect especially given the relatively minor goals I have regarding those loose ends, but if it e.g. means spending anything up to the low ten K's to give me a jump start in this, I'll happily pay it. Equipment-wise, you can consider me fully covered. Please feel free to recommend resources you *wish* you had during the learning process.

b) I am time-limited. Not in a "I'm busy 24/7" respect, but that I spend a lot of time traveling so I can't adhere to regimented schedules.

c) I like doing better than listening, reading or watching.

Thanks for any replies.
