By holding shift, you can string together whatever orders you wish, be they movement, attack, repair, assist, or wormhole commands. You can even specify attack move or FRD mode for each individual command in the queue. It sounds like you're also interested in setting constructor gatherpoints that are many planets away; this can be done by selecting the constructor, going to the galaxy map, and right clicking on the planet you wish to set as the gatherpoint.
