"It depends".  Usually yes, if there's no conflict with other AS numbers.

So if you use the same as for to MPLS clouds would you use prepen to manipulate routes or maybe hsrp???

Can't really answer that without knowing quite a bit more about your topology ie.

are you terminating both providers on the same router or separate routers

what sits behind the routers in each site eg. L3 switches for inter vlan routing or L2 switches using the MPLS routers as their default gateway on the LAN interfaces etc.

do you want to influence outbound traffic or return traffic or both ?

etc.
