It is like comparing with apple and oranges but let me try to answer this -

GTP is GPRS Tunneling Protocol which provides tunneling over IP and used to carry signaling and data between GRPS/UMTS/LTE network nodes.Check the LTE architecture http://tech.queryhome.com/27610/protocol-architecture-of-lte-network

GRE is more generic i.e. the name itself is Generic Routing Encapsulation. It is also a tunneling protocol (encapsulate a wide variety of network layer protocols inside virtual point-to-point links over IP). .

Several messages are exchanged between UE and network nodes (eNodeB and MME) during attach procedure. I want to know in which all stages timers are used to guard various sub procedures of LTE attach procedure.
