Trying to get better at sc...

I have recently (finally) been able to get online at home and play some starcraft on battle.net and have found my self at about a middle road. Can any of you give me some tips on playing better/faster with the toss?

Toss gotta be able to keep up with Zerg when it comes to producing units, you’ll never be as good as them, but you should try to build as many unit producing buildings as possible. (depending on whether you wanna go ground or air)
