you find the dual mini smg's in Egypt in the sanctuary of the scion on the head of the sphinx which you have to grapple and swing to land on it.
if your in natla mines then your lucky coz near the end of the level you fight two people then when they are dead you can then take the guns and the shotgun previously. look at something like http://tomb-raider-anniversary.com/tomb-raider-anniversary-walkthrough/Level12_Natlas_Mines/
to get the golden shot gun you need to complete the game on any difficulty doing that will unlock the cheats menu however there are no cheats in it you have to complete time trials complete all the lost island time trials to unlock the golden shotgun and the dual silver mini smg's the golden shot gun has infinite bullets and is a one shot kill gun however you do have to reload but it has 64 rounds before you have to reload so you'll be fine with bosses when you shoot them with it it will immediantly fill their rage meter. just incase your intrested I'll also tell you about the dual silver mini smg's they have infinite ammo but are not a one shot kill weapon instead they do double damage than the standard smg's
you can find both of these weapons at the pepakura file index http:/halocostuming.wikia.com/wiki/Pepakura_File_Index#Weapons it took me a while to find this site, and the SMG is only a new addition to the index, and the SMG does not have a picture next to it so look for the link in 'UNSC Weapons' that says: "SMG-http://www.vrogy.net/pepa/SMG_LIONHEART912.pdo"
Yes, you can get rapid fire on the smg's.

It all depends on the application to which you intend to put it.
look up "smg" on google and look for results in your area. there should be a few stores. if not, change the tags to something like "smg store" or "smg store near *city/state/zip*" hope this helped
