It would be a shame to swap out that B16A, but it is worth some serious coin right now.

Pretty much any supercharger made for a B16A type head should fit your bay (American market del Sol VTEC or 99-00 Civic Si) however I would put in another vote for a turbo over a supercharger. The superchargers made for Hondas aren't that 'super.'

Sure you can keep VTEC, but ideally you should use some high lift/short duration cams made for FI use, such as the ones Crower makes.
