I would definitely recommend the K-3 II, the lens, and a flash first (all new). The features of the K-3 II are excellent. I have one, and it provides excellent clarity and detail. The lcd screen on the top of the body to view settings (ISO, F stop, Shutter Speed, and EV for example) is very useful to have, and the built in GPS is handy also. If you ever get extra batteries, I would recommend Pentax brand only. A tripod brand that I would recommend is Sirui, when you decide to get one. I have two, and a Sirui K20X ball head type tripod head that I use on both of them (interchangeable).
I recommend the Yongnuo YN585EX for Pentax. I have it. It has P-TTL (Pentax through the lens metering), is easy to use, the lighting is great, and it works flawlessly. Below is a shortcut to a listing for it.
