What should I expect down the line for repairs in my 2000 Camry?

It is a 2000 Toyota Camry with about 106,000 miles on it. Replaced the water pump and timing belt at about 95,000 and just replaced a catalytic converter. Now I have an evap code where I need to get a new evap canister before inspection ($400 in parts + $300 in labor). Basically, my question is: with all these recent repairs, what should I expect to see down the road? I don't want to keep putting in $1000+ every year in repairs.
