The rtl-sdr LNA has filters integrated, no need for extra filtering.
Power is supplied via the coax. (bias-t)
They even link a bias-t on their product page: https://rover.ebay.com/rover/1/711-5...mtid=824&kw=lg
Alternatively you can buy a dongle that has an internal bias-t to supply 5 V to the coax.
(rtl-sdr v3 dongle, activated via software. nooelec nesdr smartee, always on)
If you go the way of an external bias-t i'd recommend putting a 10 Ohm resistor in series, makes the LNA run a lot cooler.
It should be fine running hot, but i was experimenting and it performance is fine at 3.3 V
