Best thing you can do for this wisteria is let it grow unhindered next year and probably the next. You may start seeing signs of dieback on the trunk this spring. I've repeatedly seen that on collected wisteria large and small in the two or three years after they've been containerized. (and for the record, this one's small to medium sized
--MUCH larger trunks can be collected and are needed, y to visually support the large flowers)...
Allowing the plant to grow without pruning --you can adjust the direction of some branches with wire, but tightly wiring and bending branches into the "finished" position shouldn't really be done at this point.
Allowing the plant to grow without much manipulatio will provide some insurance against trunk die back. I wouldn't start pruning it or wiring it, until it shows substantial healthy growth. Once that happens, the plan should be to hack it back twice a year to push flower buds--this is not all that straight forward and some research on gardening sites can shed some light on how to get wisteria to flower consistently is needed. But that's a few years off...
