Questions on sump and light

[match55]

hi there
have to bother u guys again XP
I m planning to start a sump for my 46 gal tank.
ok, here we go

I m planning to buy CPR CS 50 overflow box,
but don't know what to buy on the return pump, should I get a return pump that pump faster than the overflow or other way around.
my overflow to my sump its 3ft. the CPR 50 has a flow rate of 300 gph.
I m thinking the use max jet 1200, but it only has a fr of 295 gph, so I would love to know some recommend brand on the return pump from all of you.

and is that ok if I use flexible tubes instead of pipes, cuz I m not really good at doing the pipes thingy. XP

Lighting, I really have no idea what should I get.
they r all expensive, so I really need some good advices.
I m planning to have corals (I already have some star polyps on my live rock), probably won't goes for hard corals since I m a beginner on reef tank; but I might in the future, so i am thinking to get a light that can fit that. (I love blue light!! <3, I also saw something call moon light on ebay, r they good, anyone here using it?)

sry for all the questions, I really don't wanna mess up.
need to have a good plan so I don't waste money.
Thank you so much for all of your time!!
