1) Don't worry so much with permalinks... you'll need them because of plugins, but page name wise it's better to keep it short and simple. Let the h1/title and links coming in define what the page is about.
However, I use: /%postname%-%post_id% or /%postname%_%post_id% for most sites. Some of my blogs, I use /%postname%_%post_id%.html - I find the first two examples give you less issues with plugins vs the .html example, but I like the .html look the most.
2) The best way would be to write your own code to pull the information from the db directly. (should be able to find php samples in google) Second option is to use the rss feed and php5, parse the feed directly on your tour. (google has samples of this too) Third option is create a blank template with a real include of the wp header, put the content loop in the file, put it as a page and include it into your tour, style it from the tours css file.
For the last option, the 2nd tip on this page does the template style you need.
