I use a mach 3 turbo on my legs with whatever shaving cream I can find. I use the cheap barbasol kind, but if that's sold out, then I go the expensive route and get Aveeno. I try to limit shaving to every other day (PS, I would not use a man's razor on your under arms -- I get way too much irritation). I've also discovered this brand called Shea Moisture. They have a bunch of different products (soap, lotion, body wash, etc). I use the after shave spray and after shave lotion. Also, moisturizing every day with some sort of lotion will help shaving and prevent razor burn.
