Welcome @chaitea43, I’m Siofra_Strega, I draw from many places for my practice. We do have others that worship deities from around the world Tantra, Hindu, Buddhism, Taoism, Celtic, Roman, Greek… all over the place so no worries there!
I would start with anything that catches your eye in the courses, but maybe SpellCasting 101. You’ll find that any of the courses have great information in them to get you started & see if anything really piques your interest to learn more about it.
Weekly Witchy CHALLENGE- Of Candles and Flame there are some good entries & links about candles here & we have other information for Blessing Oil, Dressing Your Candle & Blessing Ritual
I work with Brighid & the Morrigan of the Celtic 
Pantheon & am drawn to Celtic 
Paganism/Druidry. I’m constantly learning about different things. I’m taking courses still for the crystal practitioner & working on Chakra energy right now.
There are a lot of resources within the forum also, feel free to share any information or ask any questions that you may have. Someone will get you pointed in the right direction. Everyone here is very friendly & supportive.
