Sorry, this can't be done with the current versions -- colors are either atomic
or whole-object properties (with a couple of minor exceptions). The only way
around this right now is to distribute the states you want to show over a set
of objects with different colors:
isomesh m1,map1,1.0,state=1
isomesh m2,map2,1.0,state=2
isomesh m3,map3,1.0,state=3
color red,m1
color blue,m2
color green,m3

Text objects are brand new, and can only be built right now using compiled
graphics objects (CGOs).
CGOs are always associated with specific states, so adding a label which
changes during the course of a movie would be straightforward, except that text
objects are completely undocumented. Here is a start:
# REQUIRES PyMOL 0.80
# save as cgo_3Dtext01.py
from pymol import cmd
from pymol.cgo import *
from pymol.vfont import plain
cgo = []
axes = [[2.0,0.0,0.0],[0.0,2.0,0.0],[0.0,0.0,2.0]]
pos = [0.0,0.0,0.0]
wire_text(cgo,plain,pos,'Hello World',axes)
pos = [0.0,-3.0,0.0]
cyl_text(cgo,plain,pos,'Hello Universe',0.10,axes=axes)
cmd.set("cgo_line_radius",0.03)
cmd.load_cgo(cgo,'txt')
cmd.zoom("all",2.0)
