There was no #19.2, just #19.1. #20.1 will be the final issue of this run, as you said.
Marvel made it unnecessarily complicated with the numbering. There is #1-18 written by Dan Slott, and #16.1-20.1 (5 issues) written by Gerry Conway. As you've noticed there's no #19 or #20, just the two .1 issues as part of the Spiral storyline.

While I'm on the subject, some of my own thoughts...
I personally think they should have either a) had Spiral as either its own separate mini-series (but that would complicate things more with the Renew Your Vows mini), b) released it as #19-23 (even if it doesn't really have anything to do with Slott's previous storyline), or c) had all issues as, say, #16.1-16.5 (like how Learning to Crawl was #1.1-1.5).
The second ASM hardcover has been solicited and is only printing the core issues, not the Spiral storyline, so it was a mistake having the numbering (at least for three issues) match that of the main run.
