Opening moves Warlord?

Would like to start a discussion on opening moves for a Warlord.

Any suggestions on first three techs to research?

Ships to build?

I usually start with some of the trader techs then planetology then start some ship research. I always start a shipyard first then probes and harvesters. I also build some fights but I'm beginning to think that isn't needed in the early game. I'm still trying to get the hang of the game so I would also like some feedback.

I am thinking harvester tech, advanced shipyard, offensive (for destroyer), orbital defender lasers (may have some of the names wrong).

Some of these items are probably good for all character types.
