Kinda pricey for what it is, but I got one of the goal light buzzers as a gift and it's a lot of fun to have on the wall during games.
This little net is good for 1v1’/2v2 games.

The best I could find is this
You can still tape the knob/shaft of the blade, but the heat may get the tape to gum up and ruin your gloves (sorry, I'm just assuming Houston gets super toasty in the summer).
Balls are good for practice, but it won't translate directly to puck feel. If it's within your budget, grab a few green biscuits; these emulate puck feel the best off the ice.
IMO, pads are essential but I'm probably biased as someone who plays goalie most of the time. My friends and I have tried playing without one (we just played posts) and it just wasn't the same. If you or your friend want to play goalie on ice, just be aware that the mechanics are really different since you can't slide on asphalt. And of course, check if you have a beginner's league or a learn to play league at your rink.
15-20 might be stretching it. My daughter turned 2 this winter but I didn't put her in skates yet because the attention span just isn't there - even if she did ask about it a lot. Instead I found a mini hockey set for $10 used on Amazon and she plays that out in the driveway sometimes. We'll get into skating next year.
Found this one which looks the same, but it's $35 + shipping.
LV Gridiron uses these:
Cheaper than the spotters and squishy enough where nobody gets hurt if they step on them.
I've seen a few people with the glow in the dark paint, but it seems to wear off fairly quick, especially with the friction from the tape on the end of the sticks and stuff, that's also something to keep in mind.
However; it seems they sell these as well (Found on ELT4nubs' link) Glow In The Dark Pucks for only like $7
