Han,
  There isn't a built-in method for labelling residues, but you
can do that sort of thing (and any other similar labelling) with
scripting commands. Since we didn't have a nice example of this
sort of thing, I just took a few minutes and wrote a small script
that does something along the lines of what you have in mind:

proc labelresidue { residueselection labeltext } {
  set sel [atomselect top "$residueselection and name CA"]
  set positions [$sel get {x y z}]
  set num [$sel num]
  for {set i 0} {$i < $num} {incr i} {
    draw text [lindex $positions $i] $labeltext
  }
  $sel delete
}

To use it, you'd call it like this:
  labelresidue "resid 1 to 30" "My label text"

Clearly this leaves something to be desired as far as
autmatic generation of meaningful labelbs, but that
shouldn't be difficult to add with this code as a starting point.

Enjoy,
