is it possible to sniff spantree traffic on a 1900 switch

It shouldn't keep the sniffer from seeing unicast/multicast from the monitor port, it just prevents it from being "flooded" out of this port. You should still be able to see all traffic on the switch. As far as enabling those features I don't think that it is ever supported on the 1900.
