I personally don't remember having to grind for VC2. VC3 yeah, the side missions and DLCs will be JP only, only main story is translated in English. I liked both games.
VC2 is VC1's direct sequel while the events of VC3 and VC4 occur along with VC1. See for yourself if you want to play the PSP games, I think it's a matter of liking the overall setting. Just be prepared for the lack of scout rush (which is a plus).
