It is indeed a challenge, but hopefully a fun one.
About the bridge, I was thinking of having 2 bridges, one an emergency battle bridge like in Trek, but it would consist of a semisphere or sphere that has in its center the captain's chair. The ceiling/walls would all be one giant screen allowing the capatain to judge the situation with a clear view of the surrounding space. I got this from Legend of Galactic Heroes, quite an ingenious and practical setup. The main bridge would be one outside the main hull of the the ship, similar to sea going vessels with big windows.

This would be ideal for an exploration ship, you can thus see things through scanners as well as with your own eyes and if the situation requieres it you have a back up bridge ready to go.
I'm thinking the ship should be a few hundred meeters long 100-200m
