That's a pretty decent kit. I don't use my jojoba as a primary oil, but I have it in my stock. I have all of the rest of them and several more. I think I have about 15 or more different oils and butters. The primaries are Coconut, Palm, Olive, High Oleic Safflower or Soybean, Almond, and Avocado or any of the nut oils. Almond, Avocado, Macadamia nut, and the like are nice additive emollients and are usually added to the mix with your essential oils and additives - right before you dump it into the mold. I do like to throw castor into the mix occasionally. I have a lavender bar that has it in it. I also use it for shampoo bars.
Get yourself a decent scale (kitchen types are really good - up to 11 pounds will start you off right. Also you need to get pipets for your fragrances. I get the bag of 100. A set of silicone spatulas and hi temp spoons are good, too. I also get a couple 2 quart pitchers for making my lye in. That way I can cool it down in our extra fridge while I melt my oils. Since I work in my garage, I also have a portable burner. Remember not to use aluminum pots - they react badly with the lye. I have a couple cheap stainless ones I use.
I would recommend going down to the hardware store, buying a length of 3 inch diameter PVS pipe and then having it cut in 12-inch long sections. You can use sandpaper to smooth out the cuts, but make sure they do the actual cut for you. We cut our own and what a pain! Get the flat end caps and you have instant tube molds that hold up to almost anything and are easy to clean. I use those, some Creekside Soaps wooden slab molds (which have to be lined before use with wax paper) and some custom silicone molds I made myself. I finally got my soaps up on line at Flickr, so you can see the variety I achieve.

When they superheat, they can look like Mt. Vesuvius and bubble over the edge of the mold, so you don't want to fill the PVC ones up to the top - do 3/4 - 5/6 of the way full to allow for growth. If it does overflow onto your clean counter, then make sure to get as much as you can back into the mold. Once the reaction is done, it will shrink back to normal and even a bit lower in volume. If it overflows, the volume will be irreplaceable lower. I had one of those today! My coffee soap went nuts!!! BTW Soap Hutch makes a really cool, easy to clean hi-temp plastic box mold that you can divide into bars if you want to. I want one of those in the future. Wood ones are fine, but they require a lot of prep.
When you shop for lye, use either
www.certified-lye.com or a local petroleum products company. I get a big bag and repackage it into safer plastic containers - which should be stored in a locked cabinet. I like the gal who runs Certified Lye, but I buy local, so I don't have to pay for shipping. I can also get the flake style I prefer, as it doesn't roll all over the place if you spill it like the bead version does! Make sure you mark your containers with Mr. Yuck or Poison stickers, just in case!
I'll be done with soap when I run out of the last of my coconut oil. I'm almost out of my citric acid for bath fizzies, too. I think I'll pull out the M&P at that point and play some more with it.
Have fun!
