First, check out Trouble Free Pool, BBB method. This saved my sanity while owning a pool

Second, the filter/pump should immediately be switched to some kind of timer. It's absolutely pointless to run 24 hours a day.
Third, the more efficient/better your pump, the cheaper it will be to run. I learned this the hard way by using a lot of cheap pumps and replacing them often. A good pump will last and cost less.
Fourth, keep on the pool, use it often, and don't just let it go for a week at a time and you will have no problems.
Fifth, spend the money and get a loop-loc cover if it doesn't come with one. It makes a world of difference -

Pool history:
Year 1-3 used regular old boring Chlorine tabs and dispenser with Sand Filter, replace 1 pump in this time frame that burned up. Spent roughly $700/year opening/closing/chems/treatments/etc.
Year 4-6 switched to EZ-Pool. While this was great for the sensitive skin types, it was absolute hell to keep clean/working right. Constant trips to the pool store, every summer multiple weeks during prime pool season w/out use of the pool. Roughly $1000/year.
Year 7-11 used BBB method. Perfect everything for 4 years, not a single closed pool day, never took more than 2 days to get the pool open, less than $200/year on chemicals.
Edit - Forgot about electric the first few pumps I used were between 800-900kwh/month. The Eco friendly one I eventually bought ended up using something like 200/300. Then running it on a timer for 12 hours a day only further reduced it a TON.
