You can fuse the circuit for protection, just to keep the gauges from getting damaged, but you'd need to figure a current draw per unit then multiply by number of gauges to get an accurate measure. I'd say not to worry about it.
For the senders, I drill another hole in the firewall and run anything aftermarket through it, that way you can remove the engine and/or harness independently without having to thread other harnesses through them or around. While it looks cleaner to have it all tucked in the engine harness, having to unwrap and pull it all apart is more time consuming. I usually drill below the evaporator drain tube so that anything coming out of the firewall is low and hidden from view anyway.
