hey, let me start by saying that is a nice size tank to plant.
I would say get something similar to an eheim 2213 / 15 - the filter does not have to be a UV filter.
A 3ft t5HO lighthood will fit perfectly on top of the tank. Then you need not worry about heat, and what to do with all the heat that a MH creates. you can then choose what spectrum of light you want to use for each of the 2 tubes.
Start off with flourish, and DIY CO2. Unless you have a professional CO2 system, but those are expensive.
Daltons propagating sand is nice. not too flash to look at, but the intention is for a layer of plant to cover all the visible surface substrate. flourite is another option but in all honesty is probably not going to be needed. You can then put either daltons aqua mix or JBL aquabasis under a healthy layer of sand.
Under gravel heating may be your thing if you want to add complexity, but another positive dimension to the tank.
Most importantly - what are your visions for this tank?
do you intend for the tank to be rimless? - this will affect your lighting options.
does it have a hood and stand, or just a stand.
where in the house is the tank. Is it against a wall?
I must apologise - my suggestions are seldom cheap, but are effective.
