Also, what league are you? for BSG level I would say just do a 2 (or 3 if you know how to early expand off of a T's fast expo) ling/bane/roach all in. BSG terrans wont have good enough macro to defend it. Only thing you need to worry about if they go for a relatively fast siege, they can have that by 10 minutes which makes it a bit harder. Aim for having roach and bane speed with about 12 roaches and however many ling/bane you can from 3 gas at their base by 930-10 and you will beat the vast majority of meching terrans.
In terms of openings, if they are going reactor hellion expand, start an evo (for ramp block) and a spine at 4.45-5 mins to deal with the 4 hellions at 530. If they are going 1 rax fe then you can delay that by about a minute. If you are opening 6 queen, then you can delay the evo until 7 minutes, which you still want to get incase of cloakshees. In BSG level, a 7 minute ovie sac is generally better odds than a 630 one, simply because they are slower and you can end up going in before they start building their tech.
Another thing to scout for if you see it is a 2nd gas early is probably mech or at least fast tech like early banshees. Someone better will need to correct me on this, but I believe most non fac/starport builds will get the cc before gas, rather than say rax, gas, cc builds? A little while ago, RuinD released a sizable replay pack of him doing mech. You can search through that for his build orders and take note of things like gas timings and when are good times to sac an ovie to see fac/starport counts.
If you want to play macro instead of all-inish, then make sure you have a well timed lair (8-9 minutes) because you cant get left behind in tech and upgrades. If you see double armory, you will probably either want to all-in them soon, or go dble spire to get 3/3 broods as well as the dble evo. 3/3 thors, especially with ravens, obliterate single spire play. Beware of hellion drops. 1 medivac can destroy you mineral line in seconds.
Actually I'm Silver in both NA and SEA, I was laddering in NA and playing against a Platinum Terran. I was marcoing badly but roaches eat up supplies very fast! D:
