Good shout, it is easy really. Just keep an eye on the energy and metal levels and try not to let either run down. If you do get into trouble, pause any big buildings or factory queues until you can build more energy plants or metal extractors. When you have the deficit dealt with, un-pause the buildings / factories and let them resume. You do not lose anything from pausing constructions.
The other thing to keep in mind is to build a few energy and metal storage units. This give you a bit of a buffer to collect excess resources at slow times to be used if you suddenly have to build shit loads of turrets or summing.
One last thing, you can set factory to repeat build orders. So if you tell it to build one tank, one anti air & one artillery, you can then tell it to repeat that queue forever. That way you can have like 20 factories permanently pumping out units to utterly overwhelm the enemy.
