I am about to take my car to the dyno (about 90 miles away), and I want to make sure I have everything correct for it to be tuned.

What should I check before taking it?

Right now it only has a basemap, negative boost, and running a little rich.

Should I check for boost leaks or vacuum leaks?

It has an electronic boost controller, if if that does not work, should I have a back up boost controller? Is there anything to check on the waste gate?

Also, I was told to get spark plugs one step colder than stock. What does this mean?
