im a beginner too, but this is what im learning.
Personally, id say make your own. wait till petco has a $1 a gallon sale and get one that fits your stand. home depot and lowes sell acrylic pieces pretty cheapish. Lowes will even cut it for you for free. aquarium silicone like GE 1 for window and doors for like $3 for your baffles pretty much good to go.
a 60g cube is what? 24x24x24? other options are like getting two smallish plastic totes from HD or target, have one raised a little higher and drill a hole on the top tote, add a uniseal and have it overflow to the 2nd lower tote. some say the plastics might leech chemicals to the tank, and it will look rough, but it is cheap.
as for powerheads, i dont trust the RW8's and at $80 each a bit pricey.
brs do a nice tunez for your size at $56

lights, the halo is one pretty looking fixture, but this depends on what you want to grow. retrofit t5 with the halo is the path i would take. offers the best of both worlds and quite affordable considering what you're doing.
best advice i can offer is to take your time and troll the used section for good deals, hope this helps you and gl
