I do hp as well as cp, predominantly I do cp merely because of the texture. I have a couple of soaps that I like having the rustic texture that hp imparts, the rest I like the fluidity of cp. Here's two examples (please excuse the pictures, we are looking for a new camera to purchase) - this one is hp: http://www.bunnytoes.com/storemaker/images/groupclove.jpg

Both of those soaps are nearly the same recipe and colored the same, but look completely different. I guess technically cp would be easier simply because it's less steps; but hp could be considered *safer* due to cooking the soap causes the saponification to take place much faster. And while you are cooking the soap you are periodically stirring it, combining those two things makes the likelyhood of the soap having lye pockets virtually non-existant. As for gelling cp, I throw it in the oven, many people wrap it. There's a lot of debate as to whether gelling is necessary, I force gel because I can't stand the look of partially gelled soap, but I don't feel gelling is necessary to the overall quality of the finished soap.
HP soap is usuable immediately after it is molded while cp is not. Both CP and HP require cure time, this cure time allows the soap to get milder and also makes the water evaporate making the soap last longer and be harder. In my opinion cp soap lasts longer while hp melts faster, cp tends to be denser soap, while no matter how much you bang down the mold of hp you still have microscopic holes. It's those holes that in my opinion cause the hp to melt faster, but also cause the hp to lather more.
Any recipe used for cp can be used for hp - use any oils you like, just make sure to run it through a calculator. I also like the program that gigiallin
mentioned, it's wonderful!
You say your loaf mold holds up to 64 ounces, now is that 64 ounces of oils or 64 ounces of raw soap? That will make a big difference since you need to make sure you have room for the water and whatever additives you will be putting in. Also in my opinion I don't think that coconut oil is a "soft" oil, I'd say it's a hard oil, shea butter in my opinion is a butter (harder than a hard oil). My definition of a hard oil is one that is solid at room temperature. Coconut oil also has hardening properties in finished soap, as well as lathering properties - yummy oil to use, but some people feel that coconut oil used at too high of a percentage is drying in soap.
Just to be on the safe side here's a recipe I've run through the software I use Soapmaker
with the raw soap equiling 64 ounces (with full water this requires your oils to be no more than 48 ounces):
30% Olive Oil = 14.4 ounces (that is 48 * .3)
20% Rice Bran Oil = 9.6 ounces (48*.2)
15% Safflower Oil = 7.2 ounces (48*.15)
20% Coconut Oil = 9.6 ounces (48*.2)
15% Shea Butter = 7.2 ounces (48*.15)
Full water for this recipe is 16 ounces
A 6% lye discount is 6.47 ounces
This will give you a soap that is hard, has a good stable lather, is quite moisturizing but a tad low on fluffy lather.
