As Paul suggests, EIGRP can direct number of flows to each link based on its bandwidth. However, unless all flows use equal bandwidth, don't be surprised to see actual link loading not balanced.
If EIGRP isn't an option, for routing protocols that support equal costed multiple paths, e.g. OSPF, you might "lie" to the protocol to have it use all 3 of your paths. (Since your bandwidths aren't "too" far apart, this could be an option for you.)
Lastly, Cisco routers, in their later IOS versions, support a new technolgy, OER/PfR. This technology can dynamically load balance, but there are many restrictions to using it.
In theory, pehaps the best combination would be EIGRP to initially direct flows per link bandwidth and OER/PfR to issure actual load is balanced.
Your diagram shows OSPF already being used? Although it's possible to use EIGRP across the links, if you're already using OSPF across them, you might just set each link's OSPF cost the same and see how that works for you.
Concerning Etherchannel, I think(?) like interfaces are required.
