I found some of these points in the thread 'Managing big empires - tips and tricks sought' from Space Empires V FAQs forum and some other threads. These points will be useful to new players here incase anyone might be only checking the Space Empires V General forum; so I thought that I'd repost them.
These are some key points. Some of them have been stated by others.

use those Hotkeys
-the cursor popup tool tip shows them; or set your own in Game Menu\Controls

Waypoints for ships and planets:
-select a sector, press and hold Control then press a number(1 through 9)
-on a ship turn press one of the numbers(1 through 9) to send it there.
-construction que, Queue Settings, SCROLL DOWN , Automatic Moveto, select one of the waypoints to have this que's ships move to.

Some waypoint placement suggestions are to make hopping points up to a border locaton, preferably a warp point or planet to guard where the ships or fleets can use training facilities.

planet AUTOMATIC Launch Units Remotely:
(to avoid hassle of reports of construction of units stopped because of plantet cargo being full.)
This works but requires a work around which would be nice if fixed and simplified. It might sound complicated but is easy.
-select a planet AND a vehicle in orbit, preferably a stationary vehicle like a mine or satellite
-set them both to Sentry(see why below)
-select planet, select Launch Units Remotely, select the planet's sector, select a unit type from the list that appears, repeat for all the unit types
-select Repeat Orders(allowable for a planet that is set to Sentry)
-select View Orders(allowable for a planet that is set to Sentry), remove the Senry order from the list that appears
-You will now see that the planet portrait has a Reapeat Orders icon, it will launch those units each turn to avoid full planet cargo.

Repeat Orders:
-Cargo Transport set with repeat orders; assigned to a system or several systems; route is a system's planets and warp points to gather auto launched units then launch them on other side of another warp point to be gathered by yet another cargo transport; repeat this to the empire border(can Rename the Cargo Transports to reflect the system they are assigned to.)
-or...just have unit carriers gather the units from warp points as the unit carriers travel to the border.
-also...can have smaller planets with no shipyard focus on drones because DRONES CAN USE WARP POINTS so they don't need transport to reach the borders
