Well, I do.
I play Terran, because the idea of playing 'smart' and countering everyone all the damn time really appeals to me. I can usually wreak some havoc with seige drops and marine-medic rushes... but whenever I play with my friends I usually just get rocked. My tanks die way too fast to zealots, and I'm stuck with a minor role while someone else has 50 mutalisks and 6 carriers destroying the whole goddamn map.
So...
Am I probably just not building enough? How many SCVs should I have? Depot at 8, Barracks at 10, right? Do I build an engineering lab early for the armor upgrade?
I come from a background of Generals and Warcraft 3, so I'm used to smaller amounts of more tightly controlled units. Am I just playing the wrong game?

Two armories, max out ground upgrades, build majority goliaths with sieges backing up, sweep over your enemies.

Anyway, the optimal number of SCVs per mineral patch is 3; for gas it's usually 3 if the geyser is directly to the left or above your command center, and 4 if it's anywhere else.
It doesn't sound like scouting is a big issue for you, but it's always worth emphasizing how important it is.
As far as tanks vs. zealots, that's what vultures are for. Earlier in the game you'll want to set up a minefield between your units and where the toss is likely to attack from, though once he gets speed zeals that can get dangerous if he knows how to mine drag. Either way, you should have your vultures in front of your tanks. This has two effects:
1) Vultures are fantastic at softening up zeals (and even dragoons until their shields run out, as shields take full damage from all damage types).
2) It creates a physical barrier between the zeals and the tanks. Giving your tanks a few extra seconds to wipe out zeals before the zeals get into your tank blob will make a huge difference, and may prevent the zeals from getting in altogether.
Also, like s_86 said feel free to come play with us in the G&T SC thread. We have a good range of skill levels and can probably help you improve more than a forum topic could.
Computers will walk around in circles like idiots if you do it right. Just wall in with marines and enforce it with 12-15 siege tanks and a few turrets. Then just spend all your money on Battle Cruisers and wait for yamato juice.
Against humans... you just have to play better. Spend your money constantly and expand before you run out of money. Siege tank is probably the single greatest unit in starcraft, but it needs to be backed up with vultures or goliaths (referred to as a "mech" build. "Bio-Mech" refers to marine with tanks. Bio-Mech destroys zerg, wheras pure Mech can tear down protoss shielding quickly.)

As well as every other section.
Yeah bro, in my experience SC is more about large scale warfare. War3 tactics definitely don't apply. I haven't played C&C in years so I really can't draw a comparison there.
Also I'm practically undefeated in my group of Starcraft playing friends.....yet when I log onto Battlenet, I consistently get screwed hard like a cheerleader on prom night.
Tanks don't do well in TvP without vulture backup - a 2:1 ratio of vultures to tanks is optimal - Vultures are needed to kill the zealots, as well as soak up dragoon fire so the tanks can stay alive.

I'm discovering my biggest problem is just economy. I'd stop building at like, 15 peons.
My other biggest problem is playing $$$BIG GAME HUNTERS$$$$ or $$$ZEROCLUTTER$$$ with my idiot friends.
I'm going to do some lost temple with them soon and school them. Most of them either mass Mutalisks or Carriers, so I'll go for some early game skirmish, then tech to science vessels with EMP + Goliaths. Should do the trick.
