Great little collection you have there, I built the GT3 a few years ago {there is a photo essay of it in the Auto section} and is a nice kit.
The Revell Spit is the Hasagawa Tooling and can also build the RAAF Mk 8 {I have an AM decal sheet of 4 RAAF birds for that kit}, the 32 and 48 Fw190 are good kits, the Acc Mins P51a is a good kit to build and is a little different than the standard Tamiya offerings.
The P47 builds into a very nice kit
