Sorry to jump in here with absolutely no experience on the 737 but...
Your type rating instructors will have all of the answers. Unless, of course, they're crap at their job, which I doubt.
If they aren't instructing you properly then complain about it.
Do you think that coming on to an anonymous forum asking for advice about flying an airliner is the best solution to your problem?
And before you all have a go at me about asking questions, asking for advice and asking for hints, tips and experience then don't bother. There is nothing wrong with asking...anything, but just use the correct medium.
