Hi,
Do you want to use the router as LER(LSP edge Router)?
To activate inet.0 prefixs to use labels you shoud use traffic-engineering in the mpls statement.
To put labels (inet.3) to bgp routes you should put "set protocols mpls traffic-engineering bgp"
To put "RSVP labels" to IGP and BGP routes you should put "set protocols mpls traffic-engineering bgp-igp"
and to put "RSVP and LDP labels" to IGP and BGP routes you should put
"set protocols mpls traffic-engineering bgp-igp-both-ribs" (you should have Junos 5.1 or 5.2)

It is not very clear what you are trying to achieve; but announcing
IGP into BGP is not a good idea for any reason.

Yes, if you want to use LSPs for destination prefixes and those prefixes
do not have same next hop as the egress of the LSP.

IGP shortcuts allows you to use farthest LSP along the shortest
IGP path towards the destination.
