I'm having trouble telling where the front might be from the photos given. But I'd say go ahead and start styling it now (pruning and wiring). I think you might want to style it with an eye towards repotting it at an angle, but find the front first and then take some time to consider different angles for the trunk by tilting the pot. You might find it a bit easier to see and work with if you cut down the top of the pot so that the soil is only a bit below the rim. (I did this with a tree I acquired last month, and it helped greatly.)
I'm a relative beginner, however, so take all my advice with a pound or two of salt.
