Maybe bird netting might be easier to work with than chicken wire. If you have a small area and a fence, it's easy to tie the netting to posts or tall poles you can use the fence to support. I've been using electrical conduit with metal stakes for trellises and it's held up for the most part. Here's the video I got the idea from. More expensive than just wood, but should last longer:
Another thing you could try for fruit-like things would be organza bags.

They come in different sizes and you just use the drawstring to tie it off. I never used them, but I recently bought a bunch from Amazon (not the one I linked). They probably sell it at Ben Franklin. There's a craft shop in Kalihi I remember getting these things from for our wedding, but that was 7 years ago and I can't remember the name of the place.
Did your tomatoes have any symptoms prior to dying? Ewa is really hot, so it could have been the heat. If it was too hot, maybe try giving it some shade with a tall plant or tree, or plant it on the north or east side of your house.
Okay! The author was a lady who back in the 70's (I think) had a newsletter she sent out that was finally consolidated into book form. She was raising a bunch of kids and trying to save $ so she & her family could have the house & lifestyle they wanted on just her husband's salary. Here's the Amazon on it:

You may be able to find it at a library. She was pretty popular back in the day.

Since you're in Hawaii, give it as much sun as possible.
Buy Pondtabbs and shove them into the soil. I've seen Pondtabbs at Home Depot, but for some reason they aren't showing up on the website.
If you're concerned about mosquitoes, I would get guppies instead of those dunks. Guppies are cheaper and since they reproduce, you don't need to buy them again. If you want to be super cheap, find a public pond and just take a few guppies for free.
I could be wrong on this because I only have lotus plants, but I think you should take it out of the small plastic pot, put more soil at bottom of the big pot, and plant the lily in that so the plant can grow big.

Watched about 4 melons die on the vine, but this one made it. There are two dark green Sugar Baby melons yet to be harvested.
I wish we had taken the melon out in the sun to be photographed, the indoor light doesn't do it justice.
How long did you tarp? Maybe double-layer the plastic with an air gap to prevent heat loss, and black underneath to absorb more heat? It might require weeks or months of tarping with temperature monitoring using something like a K-type thermocouple kept buried in the soil, because heat waves travel slowly.
Will you be able to attend the Ulu fest on Maui? If not, maybe try check the farmers market for some. That's where I purchase or barter for ulu as our grocery stores locally hardly if ever carry it.
Also check out this cook book. Looks pretty good.
