I don't have any rules references on hand, but here are my answers to your questions:
1) after a seamove transport, may transported troups move? i.e. does seamove transport count as a movement?
Sea movement should count as movement. Units may not move after sea transport.
2) flyers ending thier movement in a blue hex die, dont they?
Flyers have to land at the end of a turn. I know for sure this is addressed in the faq here: http://boardgamegeek.com/wiki/page/Wizard_Kings
3) may I add spots/steps to a friendly block using GP not generated in the same hex where the unit is?
I am not sure I understand. But you can only add steps to units in the same hex as the gold.
