Are you ordering from them because you're based in the UK?
You might consider ordering direct from Hong Kong, or even Olympus Airsoft. I know that Arnie (from Arnie's airsoft) ordered a pistol from Olympus either last year or the year before and it arrived pretty fast with no problems.
The 190 round magazine does NOT come standard with the Marui Thompson, you'll need to order that seperately.
I'm not 100% sure about the battery to use with the G&P kit, but I believe you'll need the AK (stick) battery.
Someone here has one of those kits, so hopefully they'll chime in.
