Well for starters, I've found that the AI is competent at waging war but absolutely retarded when it comes to when to start or end them. It seems to be fine at managing mining stations (mostly) but you ought to go out of your way to select certain places for mining. You can just select a million things if you like, but it is going to take awhile for it to chug through them (build more construction vehicles for faster building, goes without saying). I'm almost entirely not-automated now, I just let the machine run the actual battles (mostly). Because I absolutely hate military micromanagement, it's boring, frustrating and lame.
To try to summarize, I'd recommend no more automation than Ship Design, Intelligence Missions, Station Construction, Fleet management, Colonization and War waging (but not declarations). I personally manually control the former two as well as everything omitted.
For tips on what mining stuff to build and what not to build, check out your Expansion manager (or whatever it's called, it's the blue jigsaw thing). It can show you how many sources of all materials you have (sources are mines or stations that mine), how many you have stored, how many you have unfulfilled, how many are in the galaxy and maybe more. What I generally do is look at what's unfulfilled and try to scout out a source. Aculon, Nekros stones, Steel, Lead, Gold, Caslon, Hydrogen (and Helium?) tend to be pretty useful, specifically Caslon (fuel), Steel and Lead (building material), I think, are commonly necessary but like I said: Check the expansion page, it'll tell you what you need and what you have none of.
Or, in short; Build mining stations when your empire needs that resource but has no source, or not enough sources, other than that probably pass. It's also better to build mining stations in a solar system where you already have a colony (with a spaceport, preferably) because of how resources are moved around. On that note, I've also found having spaceports at every colony to be extremely useful, cuts down on refueling times, increases happiness (and therefore tax revenue), protects the colony (a little) and a myriad of other benefits.
Also, nice dubs.
