Ive had a look at your rights and everything seems to be in order. You should be able to edit pages. Did you refresh the page after creating your account? Can you try again now that some time has passed?
As for page creation, that is WAI. Users can't create pages until they have made 10 edits and the wikibot autoconfirms you. This can take a bit even after your 10 edits. I realize this doesn't help you until we get you able to make edits in the first place though
