rewrite this with better grammar but not too formal (my boss, but small company):
NAME_1 met with NAME_2 last year, and went through the information he had to get some of the points explained, as until there is a true lesson plan it is difficult to ensure this is being passed across correctly. In this he has a document where there are a number of points he has identified that are not getting into the lesson.  I have discussed with NAME_1 that prior to running this in T3 there is a bit of time to be spent in ensuring that these are incorporated into the lesson, and he has made a lot of notes in his own time on how he can do this, it just needs to be finished. NAME_1 now has the tools to create these lesson plans with the information he had, plus the information from that website - from what NAME_1 said it sounds like there is further information.
