To see every wiki you've posted to you need to go to your profile, click edit to your personal information under your username (not the profile page itself). On the "About Me" tab scroll down to the bottom where you see "Wikis you've contributed to:" Click the trash can icon of the last wiki. When you do other wikis you've edited on will appear until the list ends. There's a refresh button under this section to add back those you trashed.

Your second question depends on exactly what you mean by adding a wiki to your wikis. If you mean to your favorite wikis you would need to edit at least once on that wiki.

You can access all the posts you've made on a wiki by wiki basis via the "Contributions" tab on your profile page for that wiki. I'm pretty certain there isn't a way to view every post over all wikis you've edited on one page.
