cDub, boots are really personal preference. There are dudes trucking animals out on their backs through rough country wearing low tops type trail runners, and then there's dudes doing day hikes in mid length full leather stuff sole type boots.
Protip: Goretex liner will fail after one season, no matter the brand. I've had that be true in boots ranging from 150 bucks to 450 bucks. So just accept it. If waterproofness is important I'd recommend a smooth leather upper and you can treat with Nikwax.
Also no matter which pair you get, be prepared to get an aftermarket insole. I've tried Superfeet green and they were better than stock Asolo insoles (for me), but then I replaced them with Lathrop & Sons and those were muuuuch better.
Packs, there are lots of good ones and for backpacking I wouldn't spend more than 200 bucks. Osprey is a good start. I have a Deuter I like. Go to REI and try on a bunch with a load. Make sure they fit it to your torso length.
Boots and pack are very important, but so is what (how much) you put inside.
