Yeah, you should import The Biohazard Box Set from Japan.
Like Grey Ninja stated, the dialogue in cut-scenes are all English spoken with Japanese subtitles... but the only downfall is that the diaries/letters will be in Japanese.
Same with when you examine something... but nevertheless, its a great collectable to have as it also has different Camera Angles.
From what I know, there will be no Resident Evil Box Set to be released... but I could be wrong.
I have e-mailed Capcom about this just to clear it up... and I will reply when they inform me of whats happening.
Personally... I'm getting the Biohazard Box Set & Biohazard 4... as well as the Resident Evil Versions.
