LAMB SHOULDER JOINT, 500g- (1) How long do I roast it for? (2) At what temperature? (Celsius, fan oven)?!

Question: Thank you!! Also, I just started Weight Watchers and have no idea what the points value is (it doesn't give the nutritional value on the pack and I haven't any batteries for my bloody scales, SO, if you can help me I'd be very grateful!
Thanks again :o)
