That sounds like it would be a viable idea to take the shuttle, get 3 gathering skills and after you get your first companion change the skills.
I think only 2 of those are actually harvestable on the starter worlds, the ones for the 'mob harvesting'.
Scavenging for droids, and bioanalysis(?) for creatures.
I do believe it is only the 'strong' or higher difficulty ones that are harvestable on the starter worlds though.
