I like "baggy" style with a lightweight liner with a pad. Currently I have a couple of pairs of Dakine I got off Steep and Cheap that I really like. You will just have to try lots to see what fits right.
No underwear with padded shorts! This is really important. Full finger gloves, without padding to protect your hands are important. Any wicking top is good, it doesn't have to be bike specific. I wear safety glasses for riding. Some sort of eye protection is very important also. I shop sales a lot. You don't have to spend a ton of money. I'm a sucker for cute bike socks. I only wear tall socks on cold days or if the weeds are really bad.
