I don't really get razor bumps anywhere but the back of my neck.
But here's some general stuff.
Exfoliating before and in between shaves is important. Also try a warm towel to open up the pores before, and a cool towel to close them after. As for stroke direction, always go with the grain of your hair. I've use whatever shave gel, but many say cream with a shaving brush or using shaving oil helps reduce irritation.
I havent shaved in about a year or so, but I used disposable Sensor 3's on my face and then my T-Outliners from my Adam's apple up/around chin. I've never really tried shaving there (as I've basically rocked it since I could grow it) but my facial hair isnt that coarse, just curly.
