Why can't my switch1 see my changes in vlan information from switch0 (or 2)?
I can ping, telnet to both switches and when i change one interface fastethernet 0/1 down to up i can see them both change simultaneously, however my switch1 isn't showing the same thing as my switch0 when I do show vlan brief

Maybe i am confused on how vlans are supposed to work, are vlans that are setup for that one switch only configured for that one switch? that the actual vlan's don't synchronize accross the network?

You are correct. VLANS do not propogate to other switches unless you setup VTP. Once VTP is setup properly VLAN information will be shared amongst switches
