A "Carebear" is a derogatory term used for characters who stay mostly in Concord (police) controlled space and never ventures into unsecured "0.0" space.
Basically synonymous to cowards.
Weapon Spread refers to the random pattern of "spread out" that pellet weapons in TF2 have when fired. As distance increases, each pellet that was fired spreads out.
Some pellet weapons in TF2 include (this is not a full list, more weapons are being added to TF2 pretty quickly recently):
- Shotgun
- Scattergun
- Force-A-Nature
- Frontier Justice
Some servers use a "fixed weapon spread", which means that the pellets still spread out, but do so in a nonrandom fashion, so that each shot is the same.
This is the fixed weapon pattern most commonly used:
This is controlled by the server setting: tf_use_fixed_weaponspreads 1
. Some servers like to use this setting because they feel it removes more luck from the competition and makes the outcome of battles more based on skill.
However, one side effect of making this change is that due to the increased accuracy and reliability, pellet weapons become more powerful than they are normally.
Note that server setting does not have an impact on any other weapons than those listed above.
Some other weapons may appear to have weapon spread, but they in fact do not. They do however have inaccurate firing, and/or recoil that effects how straight a shot will go. In terms of TF2, weapon spread only refers to the situation where multiple projectiles are fired from a single shot, and spread out from each other as they travel.

The source is the original StarCraft, where the game mode for these custom maps was called "Use Map Settings":

It means the gameplay rules should be derived from the data in the map itself, instead of the regular StarCraft gameplay rules.
