You would probably get a lot more flow out of your return pump if you run 1.25" or 1.5" depending which pump you use and it's rated flow. This is around 300 gallon system? You'll be using a big return pump, and the distance you describe using 1" pipe will strangle the flow. There is a point where using too big pipe diameter will cause extra head pressure on the pump too.
The size of the drain lines depends on the amount of flow and also the distance. With a Herbie drain, don't have any horizontal lines - make sure they all have a good slope downhill. Also, install the gate valve as close to the open drain end in the sump area as possible. Don't install it under the tank when you have a remote sump.
