To start with you need to understand the difference between Invisible Thread and Invisible Elastic Thread. Loops are Yegal Mesika's trademarked name for his bands of IET. They are sold in packs of 8 as Loops New Generation for around $10 and they come with a video that teaches floating bill and haunted deck. The effects you list can be done with IT, EIT and Loops.
Finn John and Yegal Mesika also have a 2 DVD set titled Loops for around $30. Ellusionist has a three downloads for $20 to $30 each (or $50 for all three) called Guerrilla Guide to Loops. Michael Ammar has three DVDs called Easy to Master Thread Miracles for around $30 each. They cover IT, IET and Loops.
To tie your own invisible elastic bands, I'd recommend getting Mesika's Elastics which is a spool of IET. There is a download called the Millionaire's Knot that teaches how to make your own invisible elastic bands but I don't see it available anywhere. I suspect with some amount of searching on the internet you can learn how to make them. It helps to have magician's wax to make your own invisible elastic bands - You can use Mesika Wax (which is around $10 for a tin) or buy white beeswax pellets in a craft store. Other folks like Michael Ammar's magician's wax.
I would get two eight packs of loops to begin with. Expect to go through an 8 pack before you get the hang of handling them (expect to go through two or three in the first five minutes) and then the second 8 pack will last you a while. It is worth it to get the video on how to use them. Once you do that, then I'd go on to making your own.
My one piece of advice for using loops is to gently stretch them out before using them. They will last longer that way.
