You should have no problem with age verification, may I say welcome to the community and you actually read the FAQ's so you're off to a good start.
It might take a while to get verified though because the verifiers are doing this on a purely voluntary basis and may not always have the right scheduling to meet up with you. That being said they will go to some length to try and verify you.
Mine took about 2 weeks (after I turned 18) to do because of scheduling on both my part and the verifiers. Plus another week or so to get the verification status passed on to the mods.
Not only can you use propane but you can also use duster gas.
