Check the CAA website, JAA requirements are not much different. You have to seach a bit, but it is there. As far as I can remember, 150hours TT is for an integrated course. Modular requires 200TT for issue, including one 300nm cros country in one day with 2 away landings and third landing either away or back at base. I did a 400nm flight with just one away and they wont accept it. I think the P1 hrs for modular is more liek 120 and up to 5 P1/s (from passed flight tests with a certified examiner - not just checkouts with an instructor)
Oh and theory of course!
