There's not a lot to it really. On your switches


switch(config)# spanning-tree mode rapid-pvst


That's about it really. You don't need uplinkfast or backbonefast as these are incorporated into RSTP and the rest of the setup is the same as 802.1d.

No this should be entered under global. Spanning-tree portfast is still used under RSTP so you can configure portfast at the interface level buit the spanning-tree mode at global level.
