No worries at all, Jyssie! 
I was just putting suggestions on the table because I felt like you might enjoy those areas of study 
But that being said, goodness knows there is a massive amount of witchy information out there to study- so please don’t feel overwhelmed!
If you feel drawn to it, Spirit Work is anything involving spirits. Spirits of the dead, ancestor spirits, Ouija Boards, earth spirits and animism, etc. This is a very popular type of spellwork to do around the Sabbat Samhain (aka Halloween, also the Witches’ New Year), but some witches specialize in it and work with spirits throughout the year.
And yes, you can absolutely make an Ancestor Altar! 
Again, this is a popular altar to make during Samhain, but some witches like to honor and work with ancestors year-round. Tips for Beginning Work With Ancestors and Crafting for Ancestors are both good places to go for more information about honoring ancestors in the Craft 
Again- I don’t want to overwhelm you with any of this, Jyssie! Feel free to explore what calls to you when you feel ready. There is always more to study, so there’s nothing wrong with pacing yourself!
Good luck and many blessings to you!
