I've got the UPR as well and no gripes. The damn orange flange that Ford uses is really fucking annoying though, but there are walk throughs on what to do if you have it.
I would opt for all the options and go for the biggest options on all hoses and valves. Why not? It actually improved my MPG a little and now I have better protection for my engine with very slightly better performance, so I came out quite pleased.
