Hmm, well given that it did manage to setup all of the tables correctly I don't think have a different port is causing the issue. And I'm not sure what you mean by 2) remove plug-ins...How do you have plugins installed if you can't login to WordPress? Did you copy them into the folder directory manually? They still shouldn't be activated, so I'm not sure that's the issue either.
Take a look at this page below and the "white screen of death", try going through those solutions and lets see what happens.
