If this is one vs one and ur opponent is either terran or protoss i dont think you will need a bunker its a waste and it slows you down. Even if it was a 2v2 teching like that is a real no no if you were going against gosu players. If u manage to pull it off good stuff but also pulling this off requires a crap load of micro.

You dont really need to quickly build another depot that early (unless your playing it safe) i rather use that 100mineral to building a factory and quickly get moto bike depends what opponent is going to do.

Well a pretty good strat otherwise it seems you like to play it safe. Also it looks as if your a 2v2 player since your building rines and bunker probably to stop zergling attack. When your first supply depot is finished that SCV should explore while another one comes to build a rack.

Ehh..

All depends on what your playing against, I'd always get 1-2 marines incase of goon rush or just a wondering probe that could scout you and give away any rush you had planned.

If your doing that, I'd go with vults and try to work on your spider micro :) just contain whoever your playing deplete their minerals, let em shrivle and die, and expand as much as possible, making each expo very well equipped (incase you get dropped... i hate that =\)

Always try to see if u can sneak something in on another player, like float a factory or barracks into their base, 4 vults with 12 mines can do ALOT of damage to an un-expirienced, or even a progamer, if u micro enough. Ive had a friend take out 5 goons with 4 vults 12 mines + a drop ship :).

I'd not really try to plan this out too much, or stick to any kind of a plan, just make it all flow, dont tech up too fast, or you will be helpless if he/she scouts and notices your defenseless.
