hmm, the templatesystem of vb3 is completly different to vb2's so most likely you can't use the style you want to buy for vb2 with vb3 (ok, the graphics and maybe the header and footer with some work, but not the whole style..)
yes, you can translate your board in one days if you have the time on your hand to work the whole day which is hard
normally you don't have to be a vb guru but be carefull, sometimes it will happen that you'll translate var-names and then the site won't work
