Answer
# 1
MPLS is a one of a technology to route packets fastly in 
the internetwork, were as OSPF is a Routing protocol.

MPLS technology is nothing but adding a lable contains 
virctual path to reach the destination network(VRF) to the 
data packets. once the labled packets are received by the 
router,the packet is switched directly to next router 
through the virctual path based on the VRF details, This 
means there is no need for routing table look up, and 
because of this the switching is very faster than other 
technology.

As far as i know that Link-state routing protocols such as 
OSPF flood routing information among a set of routers that 
are not necessarily adjacent, whereas label-binding 
information is distributed only among adjacent routers. 
This makes link-state routing protocols unsuitable for 
distributing label-binding information.
