I recommend that you look at a book on standard C
language syntax and data definitions. The wikibooks
are pretty good:
http://en.wikibooks.org/wiki/C_Programming
For your question:
TOS_Msg is a structure definition;
TOS_MsgPtr is defined as a pointer to a TOS_Msg structure;
TOS_Msg gRxBufPool[QUEUE_SIZE] defines an array of TOS_Msg structs;
TOS_MsgPtr gRxBufPoolTbl[QUEUE_SIZE] defines an array of pointers
to TOS_Msg structs;
But if you didn't know that already, the above will make little
sense until you read the C book...
