If I get an Acan where should I place it in my tank? I am running 130w of PC lighting. What about flow, do they like low, medium or strong? If I spot fed how fast would they grow/spread?

There are a dozen species of Acanthastrea and they all have different requirements. You'll want to be more specific of which type of Acan you are looking to get.
With the amount of lighting your running, you should be able to put most Acanthastrea anywhere. In my experience, some grow better under brighter lighting, but show better coloration under lower lighting with a high Kelvin rating.
For fleshy Acanthastrea like A.lordhowensis, low to medium flow. You don't want to flow to be direct, so the coral can't expand.
For harder, bony Acanthastrea like A.echinata, medium flow is good.
Growth depends not only on the species, but also if it was a tank raised coral or wild coral. In my experience, Tank raised Acans are already adjusted to aquarium life, and grow faster than wild Acans. Tank raised are usually stronger, and more forgiving, if the aquarist makes a mistake or two. I've seen whole wild colonies perish from mistakes or stress.

I'm looking at the Aussie Acans...I believe they are Lords.

There is not a lot of information out there on them just yet. I'm experimenting with some now. Starting them off low with low flow.
I picked up an Australian Acanthastrea hillae and after a week, the top of the coral looked unhappy. Possibly from over lighting. I have it next to the lords and they look fine. I had to move the hillae.
That's why no matter where you put your new additions, you should keep a close eye on them. If they start to look poorly, move them right away.
