For trimming i just brush out my beard and use scissors to get the long strays and try to get them same length as the others. (Only when dry). I always wash and condition with a beard shampoo and conditioner. After drying i use either oil or beard balm. I like the balm because it is like a leave in conditioner and it feels good on the skin under my face curtain.
Always use a good boar brush. Cant beat them.
My wife says i have more products for my beard than she does for her hair!
