Hi Chandu,
let me start with some brief answers, we can dig deeper then if you like.
What does it mean by "Maximum VLANs supported locally" ?
The number depend on the platform.
Example: Catalyst 2960 Data Sheet: Max. 255 VLANs
Much more important: Low-end platforms are limited in the number of spanning-tree instances they support.
Example: Catalyst 2960: Max. 128 instances
And the output is showing that the present verions is "VTP Version 2" and again at VTP V2 mode it is showing as disabled, why?
It means the switch/IOS is v2-capable (but running v1).
This output- line in your IOS is somewhat misleading, other IOS provide a much better output:
VTP Version : running VTP1 (VTP2 capable)
Can someone tell me what is "VTP Traps generaiton" ?
You can enable SNMP traps for VTP events (SNMP traps are sent to a management station):
Sw1(config)#do show vtp status | i Traps
VTP Traps Generation : Disabled
Sw1(config)#snmp-server enable traps vtp
Sw1(config)#do show vtp status | i Traps
VTP Traps Generation : Enabled
And also at the end what does it mean "MD5 digest" i believe it is reffering to VTP password, but i didn't set any password for this switch yet.. but on the right side of that it is showing some hexadecimal values what are they?
Have a look at this discussion:

Configuration last modified by 0.0.0.0 at 3-26-93 14:35:34 --> What does this exactly mean?
Local updater ID is 0.0.0.0 (no valid interface found) --> what is local updater ID, i thought it wil be an IP address, but again it is showing like no interface found?
The switch hasn't received "better" VTP information from another switch so far and uses its own information (local vlan.dat).
0.0.0.0: It seems like it doesn't have an IP address configured and up/up.
