The snail really shouldn't be in there while you're fishless cycling. If you want to keep it I'd put it in some clean water and give it water changes until your cycle completes. If you're not bothered then I'd try to euthanase it humanely rather than subject it to toxic levels of ammonia & nitrite.
I also found that artificial ornaments had a tendency to lose paint during a fishless cycle. I assumed they were just badly made but perhaps the paint does react with the ammonia.
You can get large bags of filter wool online that will last for ages. I bought 250g for the equivalent of about $4 in the UK, can't advise you where to get in the US though.
I can see why your husband doesn't trust the tap water since they admit there is a risk of contamination! I would be reluctant to trust this for fish since the level of contaminants deemed safe by water companies for human consumption is often not safe enough for fish. It's a risk. I would try to find out more about your spring water or consider using RO water, personally.
