With suitable IFR time, I'd work at becoming unrestricted, then complete the IRI add on to the FI. If you have 30 hours P1 MEP (and thence CRI ME) then that would make you very employable almost anywhere.
Not really(unfortunately), most of the bigger schools will not take already qualified CRI's, they promote from within unless you are very experienced on twins.
With your multicrew experience just get your self an MCCi and TRi if you can, guys like you will be very much in demand teaching the advanced phases of the MPL soon.
