You can get Isc so two would be 18 amps which is under the 20a of the controller, but does not leave much margin. If the panels are flat and not usually aimed directly at a high sun, you could do it. IMO go for it.
(The risk of going over 20a for a time is the controller will overheat and fry itself at some point. Brief times of cloud edge effect don't matter.)
Yes if you go series with that controller you will get 9 amps instead of 18 with parallel.
No point going MPPT for another couple amps (if you even get them) when you already have a good controller. I have used a LandStar-very good controller.
