Yes, you'll create an etherchannel on this switch and an etherchannel on the other side. Those ports will be treated as a single link with STP. You don't want to create an etherchannel on one side and nothing on the other. You'll end up with a loop that will bring the whole network down.
In your switch, you would do something like:
channel-group 1 mode active
channel-group 1 mode active
Those will pair, and then you'll do that on the other side as well. If you're wanting to put an address on these, you'll need to configure each port with "no switchport" before doing your channel group. You'll also need the same exact configuration on each port. Otherwise, the interfaces won't pair.
For a particular connection etherchannel always uses the same physical link. The connection can be defined a number of ways depending on the switch capabilities eg. src/dst mac addresses, src/dst IPs, src/dst ports etc. But however it is defined for the same connection the same link is used.
What this means practically is that if there is one connection that needs more than 1Gbps then adding another port and configuring an etherchannel wil make no difference because it will only use one physical link. If, on the other hand, there are multiple connections then etherchannel could indeed help.
Just to clarify, if the transfer is between the same two devices then using etherchannel will not help. To be more precise it won't help that specific connection but it may relieve the load by moving other connections to different physical links within the etherchannel.
If the problem though is for transfers between two specific devices then possible solutions are -
1) move them to the same switch where you can utilse the switch fabric which will give you much higher throughput
2) if 1) is not possible then you could purchase a dedicated switch for these transfers and move the relevant servers to that switch
3) 10Gbps is obviously an option but i doubt it would be worth it for just a few data transfers
