have some poppies growing out front, sorry don't know what variety, the
were here when i arrived, but is it worth dead-deading them? will it
stimulate it to produce more flowers

No.

what about hardy geraniums? they're about to burst into flower too?

No point in dead heading individually, but once the plant has finished
flowering, it can be worth getting rid of all the flower stems to tidy
up the plant.
