yes, normal nuke blocks work with the ported version.

let me explain the difference between blocks and modules.

a block is, as iaco said, a chunk of info on your main nuke site. there are tons availible for download at many sites.

a module is a whole sort of 'program' within the nuke directory. it has its own page(s) and contains much more data then a block. modules are also availible from many nuke sites.

think of the port as an 'addon' to the nuke site, so its only within nuke, it affects nothing in the nuke base.
