A 1HP inground pump is MORE than enough for your pool: a 33' x 52" pool only holds around 22,000 gallons. Optimal MAXIMUM circulation is around 60 GPM, but you probably want more like 48 GPM.

A combination like this:
Hayward S244S Pro-Series 24-Inch Side-Mount 1-1/2-Inch Vari-Flo Valve Pool Filter @ Amazon
Hayward Super Pump 2-speed 230V w/Switch @ A1PoolParts
would work exceptionally well and be very efficient to operate. You would leave the pump on low speed except when vacuuming, backwashing, or cleaning up, and you would definitely want the smaller pump!

But, I'm not sure if you are planning to use an IG pump and filter.
