Is this power steering?

yes, that is the power steering stuff you'll need. looks like the system has been open for quite a while so you will probably need to rebuild it. pumps and brackets shouldn't be too hard to come by, you can buy most of them new but they are fairly pricey
 
yes, it is. the only thin is all that stuff probably would be better off as cores. you could just swap it, get the pump and new hoses and bolt it up and get lucky but likly its in bad condition.
