I am in a very similar situation, and the info that I was given by the CAA, is that after passing the required 14 exams, you just need to pass the check ride on the sim. I haven't yet figured out how I am going to do this yet. I think I am going to need another pilot as well...
Incidentally, I have looked into this Bristol G/S as well, and it looks quite good. It is divided into two modules (8 exams/6exams) After completing each module you travel to the UK for two weeks for a review, and then you sit the exams. It seems that the pass rate is extremely high. However it will cost you a bit more cash - and our dollar is not very strong compared to the pound.
Hope this helps.
PS I have looked into the JEPP Course, and you have to order it from Europe. The North American division does not stock the kit.
