It's true that Teatimer isn't available in the Spybot 2 versions,yes.It's available in the Spybot 1.6.2 version still,as far as I'm aware.
This is half a guess,and half vaguely remembering it posted somewhere,but I believe teatimer might not have been used anymore partly because other antvirus and/or other antimalware programs with it's own real-time protection began prompting for Spybot to be uninstalled completely,instead of suggesting to disable teatimer to avoid possible conflicts or any other kind of a different solution.There's a page about compatibility with other resident protection tools here:

I don't know,and haven't noticed anything posted about it.
Yes,it has in the paid versions.There's a page about that here:
