Chances are any of the op-amps would work well, particularly if you can set a dead-zone around zero.

If you insist on having a balance control then I'd look at the LF356, just from 5 minutes glancing at the datasheets - there's an example of how to connect the balance trim pot (I'd select a multi-turn pot for this); but I doubt that you really need it given the low gain you need.
