What are your goals with the tank?
What size tank? That will determine the size of heater you'll want.
What type of filter? Inline heaters can work on canister filters.
I would buy an electronic wall outlet timers for the lights, they are much more forgiving in a power outage situation (they will hold their settings, and are dead silent - the mechanical ones make some sound).
Brands that I like:
Filters - Aquaclear for hang on back, Eheim for canister
Heaters - I only use inline Hydor heaters, if not I would look up a titanium heater with a secluded temp control option.
For the N cycle, it depends if the tank is planted or not.
API is a good starter kit for the cycle, after that you'll only really use the NO3
and pH tests and the odd time, the ammonia test. A $20 pH pen from amazon is a very good investment. Make sure it comes with calibration fluid.
liquid kit is also a very handy tool to help understand your water.
