how to get above ground pump to work on a below ground pond.

Hello,
I am in the process of installing a pond. it is about 15x8x4. I
already have the plumbing ran except for the skimmer. I am using a 4"
drain and using mortar for the lining. I already purchased the pump.
it is a 1 1/2 hp hayward aboveground pool pump. I recently poured the
slab for the pump and filter to sit on. When i bought the pump i was
told that it wouldnt be a big deal to prime it if it sits above the
water line. The more i read the more i get frightened. Once i install
the pump on the slab it will probably be about 8" above the water
line. Does anybody have any idea of how to prime this setup?

Another question i have is on the skimmer. Anybody have recomendations
on what skimmer to use for a mortar lined pond? or any installation
tips on it. or if i should even go through the hassle of putting one
in. Also how would i seal it up . along with the 4" drain at the
bottom.

Sorry for the rambling. So many questions im getting a headache.
Thanks in advance for the help...
