Let me see if I have this straight-I add some tylose to Wiltons fondant it will make gumpaste...
question 1) how much tylose say for a small box
2) do I just knead it in
3) then how long do you let the gumpaste sit before using,
refrigerate it or not
4) which is best to use - Crisco, veg spray, or cornstarch on
the mold to prevent sticking
TIA,

Gumpaste should be made in small batches, but can be frozen if a large amount is made. I don't recommend Wilton fondant, but Pettinice does work well.
Take a fist sized piece of fondant (even homemade) and add about 1 Tbsp. of Tylose. Knead it in in small amounts until the fondant becomes tacky. Rub shortening over the ball of gumpaste, wrap it in plastic wrap, place it in an airtight container (zipper bag or plastic tub), let it sit over night.
Use cornstarch inside of your molds. Sprays can cause the gumpaste to crust too quickly, and strangely enough, shortening can make it stick and stretch as you try to remove it.

It is better to dust the gumpaste before pushing in to the mold, so the details of the mold don't get filled with cornstarch.
usually gum paste made from a different recipe than fondant, but fondant can be enhanced with Tylose or Gumtex to approximate gumpaste.
If you need only a small amount, just sprinkle some on a small portion of fondant and knead it well. You will be able to tell as you work with it, if it is drying quickly. If you roll out a small piece, say pea sized, into a flat disk, it should begin to harden within minutes.
Thanks for the info Michelle
I can get Satin Ice, is that similar to Pettinice? I have some leftover Wiltons fondant, so I wanted to try to save some $$.
The gumpaste will be used to make a baby crib-do you think I can use the Wiltons just for that part, and use Satin Ice for the other accents...what do you recommend?
is that because I don't have enough tylose in yet, or too much, or I just need to knead it longer??? 
Takcy? I would add some shortening to it if it is stiff. Tacky just a little corn starch/powder sugar mixer. I also let it set for at least an hour (over night it better) to let the powder marry with the fondant.
okay, so I'm kneading in the tylose-if the fondant feels more dry and stiff than "tacky"; is that because I don't have enough tylose in yet, or too much, or I just need to knead it longer???
If it feels that dry, try adding a bit more fondant to it. If you add too much shortening, the gumpaste will take a VERY long time to dry (I learned this the hard way).
The Wilton will work for your project. I just wouldn't use it for flowers. It becomes very brittle as it dries. The Satin Ice is much softer and you can make a good gumpaste with it. If you have cold hands, use a little less Tylose. I have very warm hands which melt most gumpastes, so mine has to be fairly stiff. When it sets up, it will be stiff. You will need to knead it before using. I don't recommend warming it in the microwave. It really makes the gumpaste react strangely. 
Another tip for too stiff or dry gumpaste is to knead in some of your gum glue. I like Tylose and water, some people use egg whites, some just use water. It's another one of those things where you experiment until you get what works for you.
Good luck. I hope this helps.
