Orbital eva: Module with 1 and more astronauts, second rocket (the one after atlas) or Atlas with booster strap on. Eva suits researched.

Actually, you don't need the boosters for an Orbital EVA with the Mercury/Vostok. Just use the Atlas/A-Series.

Lunar passing, Lunar Orbital: Uhh don't remember, shoot me if I'm wrong but I think it should be module for 3 or more, booster A (maybe B don't remember) and second rocket (again the one after atlas), but you may need booster strap on for it.

You don't need to use the Apollo/Soyuz at all. I rarely do in fact....the Gemini works as well for anything -but- the actual landing. You use the Kicker-A for anything but an actual landing, which uses B. Again, no boosters required for this one.

TIP: I have read somewhere that you should keep ranger/sputnik safety level high since in the moon mission or somewhere one stage is rolled on it's safety level.

False. One stage is rolled on the amount of Photo Recon you've got, which is gained by lunar flybys, probe landings, manned passes and orbitals.
