Layer 3 Campus Solution

My organization is planning to deploy campus IP routing end to end, all the way to the Edge Switches, using Catalyst 3550 EMI series switches. Is it possible for us to activate dispersed VLANS using VTP across active IP routing interfaces?

If so, can we still maintain layer 3 instant failover(perhaps using HSRP) without the conventional Spanning Tree Protocol Fail-Over.
