Is BGP the solution here?

Imagine I have a 2600 router serving as an important router connecting (MPLS) my Continent to another important branch overseas.

If I want to minimize the router point of failure, is my option here set up a new router (perhaps a 2800 and do BGP)? Assuming I do not have budget to setup a backup link, In this case, the respective single router is a 2600.

In this case it is not actually about BGP or not. For redundancy purposes you could very well use OSPF. It has faster convergence if you stick to the default parameters. (I am actually no fan of tuning convergense parameteres). You should agree with your provider, and for the MPLS VPN PE routers they run BGP. BGP is primarly a routing protocol for connecting ISP's. (autonomous systems). An for MPLS providers M-BGP (multiprotocol BGP) keeps track of the vrf's

So it actually only depends on your budget.

Is the branch office connectivity so important that it justifies a backup link.

The answer to that it is only you that can answer :)
