Her recipes are reliable but make a lot of soap so they'd need to be scaled down. As Genny suggested, I recommend starting out with a batch of 1.5 to 2 pounds - not so small that you get into measurement problems, not so large that if it doesn't turn out well you've wasted too many materials.
You can also find good basic recipes on the soapqueen blog hosted by Anne Marie of Brambleberry or our very own Amanda's Lovin' Soap blog.
Some basic advice:
Safety first - goggles, gloves, closed toe shoes, long pants, long sleeves.
Mix lye in stainless steel or HDPE pitcher. Glass can be damaged by lye and shatter unexpectedly, even Pyrex
Get a good digital scale and weigh your ingredients in grams if possible. If you have irregular amounts, round down for lye, round up for oil
No aluminum utensils, vessels or molds, it can cause a dangerous chemical reaction in contact with lye.
Run every recipe you attempt through a
lye calculator to check for accuracy.
www.soapcalc.net is a good one.
Finally, always unplug your stick blender before you clean it. Don't ask me how I know!
Hope I haven't scared you off or insulted you by telling you things you already know. It's great fun and very satisfying!
