Re: local computer installation
If you have a local computer with windows or a Mac, you can always have the install of WAMP or an install that is similar. Do a search for apache, php and mySQL local windows install in google and you will find that there are many packages out there that can run them on your local computer instead of IIS. Packages like WAMP have all the packages together and a walkthrough on getting them all installed.
As for bbPress and WordPress installation together, I am involved with WP as well and can for sure tell you that they will never be packaged together for a single install unless someone makes their own release of the 2 packages together, but will not happen from Automattic because they are run completely seperate.
Does that help?
