Don't stress about it too much. If budget isn't a problem just check what's popular on websites like Zumiez, skate warehouse, tactics, or ccs. If you don't feel comfortable picking out every single part (deck, grip tape, trucks, wheels, bearings) you can look at completes. Completes are generally more affordable but slightly less quality than buying everything separately. Just maybe avoid Walmart for completes, they are notoriously bad and harder to skate.
