Firearm licensing question?

I recently got my class A LTC (no restrictions) in MA and the issuing officer was very limited on information he felt like giving me, (and its a pain in the ass to contact the guy which is why I’m askin this on Yahoo now)
I’ve been going through the paper work and maybe its right in front of me but my questions are…
1. Can I carry a concealed weapon?
2. Can I accompany a non-licensed person? (aka if I go to the range or something, allow someone whos not licensed to operate one of my firearms) It seems as though thats how it’s worded I’m just double checking.
3. What else can I possibly do that I’m not thinkin of? Other than basicallly purchase any and all large cap weapons other then a machine gun. oh and can I legally transport a weapon through RI or ME because I go to both often and would like to go hunting in ME and there are a few good ranges in RI. (as long as their locked up and ammo seperated)
MA is extremely strict on its licensing polocies.. the LTC stand for licence to carry, the class A is for high cap firearms

MA private gun sales question?

I am a MA resident, with a class A unrestricted LTC. I’m trying to buy an H&K P2000 9mm through a private sale from a friend who is a non FFL dealer (private party) in Texas. It is my understanding that although the weapon is not on the MA approved handgun roster, the sale can be made as long as the proper transfer paperwork is filed with MA, and that basically the approved handgun roster only applies to firearms that can be sold by licensed dealers in MA, and therefore would not prevent a private sale of a gun that is not on the roster. Could someone with a working knowledge of MA regulations chime in on this please?
Thanks very much in advance!!
