There is a blog post I often quote when the issue of "seeding" a new site comes up:
Your New Site: Asking the First Questions
Every community is different and every launch is different. I really don't suspect there will be a problem with asking some of your favorite questions here, but be aware that it can be overdone. A site can start to look somewhat forced and uninteresting if folks are just reiterating documentation or just spitting out questions because they've already been answered elsewhere.
I suspect many of these questions will be asked again organically if you let them come in their own good time, but asking questions you recall from having interesting problems in the past can be a great source of interesting content for a site. Have a look a the blog post I linked above to at least be aware of issues. And then just relax, let the whole thing come together organically, and enjoy your new site!
