Is my plan screwed? If I set it up as I planned, sucking water through

the
pond, but before the slope? FWIW, the pump is rated for a little less
than
3000 gph at 4' height.

The idea of pushing water must mean to place the pump below the water
line so it doesn't have to prime itself. Once the flow is started I
don't see how the pump operation could be any different, because the
pump action is the same whether it is above or below the water level.
I'm not familiar with this kind of pump, but you might benefit from a
priming pot.

You may be right about the below water level location. Rereading the
'installation hints' for the fifth time, the other statements seem less
absolute than "The pump is designed to push water, not pull it." I'm going
to see if I can put the pump at the bottom of the wooded area and push water
uphill for the second half of the transit.

BTW - I have a priming pot, which I got along with my pump from azponds.com.
The pump is a new sequence 'value' model this month and I think azponds is
the only distributor.
