Yes, TPE or ICN would be fine. Distance for Asia stop-SEA > Distance for Europe stop-SEA, you're good.

Very much so, it's Ryanair's hub.
FWIW, Germany, France and the UK all charge a departures tax, so using those nations as a departure point for a longhaul journey to Asia after a stopover will add a couple hundred dollars in taxes to your trip or more (the charges can go up if you're in a premium cabin). You can avoid that by having your Europe stopover be one of AMS, ZRH or DUB, or some other country that does NOT charge APD. If you route through LHR on a tight connection to CX you'd be OK (just stay away from BA on the longhaul segment, unless you want to pay a large fuel surcharge for the privilege).
