Don't suppose any of the admin addict admins would do a step by step guide to getting a vb forum and wordpress home page up and running like this site has, could help a lot of people as anywhere Ive looked including wordpress and vb site haven't helped that much. Maybe i'm just being blinded by the fear of breaking my forum
Its not that difficult. Install your vBulletin to /forum (or move it there if its already installed) Install wordpress to your site's root. The hardest part will be skinning wordpress to match vbulletin, but thats usually only a 2-3 hour job for good coders.
