Point 1-
Currently we have 1 ISP which is terminated on Router 2951 and now we are planning to add 1 more Router 2951 and 2nd ISP link.
Need to achieve Failover and load balancing between these TWO Router,
please suggest how can i achieve this.
Point 2 –
Also if possible – can redirect FTP Traffic to Separate link.
Edit
We have 2 Router 2951, both having 50mbps Link terminated on each router.
Achievement – we have to do equal load balancing,at a time both wan link should be used and WAN Link Failover,
Example – At a time both link should be used and if 1 link fails the other link should take over, i.e. all traffic will pass through ISP 2 if ISP 1 fails.
this we want to achieve with IP SLA on 3750x switch
Attached is the network diagram for reference.

Are you running BGP with ISPs? Or just defaults towards Internet?
You should propably configure HSRP on the internal side between routers to have single default gateway for your network - or multiple default gateways if the inside will be segmented in VLANs.
If you're running BGP and you do have PI space, announce it on both links, then try to tune using the BGP traffic engineering features.
If you don't have BGP, you can try to use Performance Routing coupled with NAT, because you'll need to match outgoing traffic with properly selected source IP addresses (your ISPs should do uRPF and check what source addresses you're using on links they provide you).
As Mike stated, topology drawing would benefit the discussion.
