millersoap.com has a lot of great info. Including what different oils do in soap which is really useful. You can find some lye calculators at different sites (brambleberry.com has one) which you can use to make your own recipes.
for beginners the Handmade Soap book by Country Living is excellent. It has very basic recipes that are pretty easy to understand and most only use about 3 different oils (coconut, palm and olive)
For more complicated stuff the Soapmakers Companion is great but it gets pretty complicated and some of the recipes call for luxury oils which are pricey when you are first learning and might really have an "oops"
You should be able to add Eos to any recipe **BUT** I just want to warn you, citris EOS can fade pretty badly in soap, it can be tough to get tangerine and bergamont to stick. It is sad...you might want to save those for bath oils or maybe even make bath bombs for those. I made tangerine bath bombs once and they were super yummy!
Lime and litsea EO, I had better luck with and lemongrass, while not technically a citris, works very nicely in soap.
For acne, tea tree, a mint like peppermint or spearmint and lavender are great together and the mint makes it a nice morning bar.
What type of oils do you have availible??
