Scott,
I've moved this and your other topic to the "Working in ARCHICAD" forum. The "Other Problems" forum isn't the place for these kinds of basic operational questions.
I feel your frustration at a huge leap from AC 9 to 22... but you should realize that at a certain level it is almost like learning a new program compared to AC 9 and it will take some serious work paging through the user guide or getting some by-your-side help. It isn't just lack of PlotMaker and the integrated layout book... model view options, building materials, intersection priorities, the Tracker vs the coordinates palette... a zillion new things to adapt to.
To add to Richard's response... your concern was with Publisher. You have to set up your Publisher set to include what you want it to include. A layout with your site plan won't necessarily automatically appear there - at least for a manually managed publisher set. You have to drag it over. You can have as many publisher sets as you want, too.
The Navigator has a variety of ways of appearing in the user interface - drop down/pop-up, floating/docked single-column view ... or what I think you might find most useful setting up your Publisher set ... the Organizer view, which lets you see two column at once ... e.g., your Layouts and your Publisher set for drag/drop organization.

It's a big journey, but you'll be glad you upgraded.
