switch to protoss to get free masters then switch to zerg for free GM because you should have at least the basic mechanics down by then.
If you really want to stick with Terran though, good on you.By the time you get to Diamond + you will far and above the actual skill levels of other diamond/masters zergs and protoss.
For a bronze player i would say focus on spending your money. Always have at least 1 SCV que'd on your CC's at all times and keep building barracks.
You can hotkey all your production to the same key and hit tab to go from rax -> factory etc but be careful about building the wrong units if doing this. Whenever you have units que'd and you still have extra money, build more barracks.
In bronze it's probably OK to a-move your army but you will eventually have to learn how to position and split in order to win games.
Teamliquid for build orders.
