Lots of great advice in here, and I admit I didn't read it all, but here are some simple bullet points to remember

Game strat:
- TvP has some nice timings where you can be a lot stronger then he is. My favorite is to Bio FE then push as my 3rd & 4th medivacs come out.
- Don't get to late game vs. Toss!!! Their 200 food ball will beat yours (almost) every time regardless of upgrades.
- Don't let P get 3 bases or it's over (mostly)
- If you fail 1 & 2 then you need to drop harrass him to death and expand. (Generally) The only way to break P then is to smash wave after wave against his ball to weaken it, whilst you out reinforce him.
- If you don't play off one base then beware the P one base attacks (4/5 gate, etc.). FE's require leading scouts far enough away from your base to let you pull SCV's to repair the 3-4 bunkers you MUST build vs. 1 base P.

Composition and Tactics:
- Bio is still strongest in the meta game, though more people are playing around with mech
- Even as bio you have to react to his unit comp. Zealot heavy = more marines, stalker heavy = marauders en-mass, archons = ghost (EMP), collosi = vikings
- Use stim and have plenty of medivacs
- If you let him ball, don't engage directly. Drop, harrass any vulnerable expo's, maybe even split your army and try and flank him (to kill colo)

Rules of thumb:
- 3/3 is a must for bio, and I like to get starship armor for medivacs as well when I get an armory.
- One you are up and running on 2 base, get double Eng bay to pump upgrades.
- EMP is a must against HT's and Archons, but is awesome against other balls too.
- If against HT's, bait him to storm then stim back out. With plenty of medivacs you can counter back once he has blown his energy, end your emp's will be more effective.
- When using EMP high priority targets are HT's, archons, and immortals in that order.
- It takes 14 vikings to 1 shot a colossi. When engaging more than a couple, feint in and out with your army to drag the stalkers forward, and hit with mass vikings from the sides.
- Trading vikings for collosi kills is ALWAYS correct (as long as you kill them). Collosi take a long time and a lot of resources to replace, and vikings don't. If all you do is trade away vikings for all his collosi then you will pull ahead as long as you keep macro'ing.


Anyways....some random thoughts. Sorry if I repeated anything from above.
