First of all, if you are not sure how to do this I seriously suggest you enlist the help of someone locally who can help. It is possible to kill yourself or burn your house down if you screw up with electrical work.
To run it balanced you'll need to connect it as you stated but also jumper H2-H3 on the primary otherwise no current can flow. That puts the 2 primary windings in series and also the 2 secondaries so it is a 1:1 transformer.
The full VA rating at 120VAC assumes you are running the 2 primaries as well as the 2 secondaries in parallel so each winding carries half of the current.. Running balanced you will have them in series so VA rating is half since full current runs through each winding, not half of it.
