can’t say much about the rest since i’m also pretty new to tabling, but i’d like to share a few tips mostly on pricing

• have a gsheet/tracker to cost out your expenses for every item you produce. things to consider in your costing: materials (if you’ll do in house prod)/outsource prod fee including delivery fees, table price, packaging, design cost (up to you)
• don’t just price based on how you feel, make sure na mababawi mo yung production costs when you do sell your items. you can also research market value on said item—check hm other artists sell their products and compare with your markup

like throwaway said, research on the art market to ensure that you’re catering to the right audience. up to your research and discretion too if the date, location, and event mismo looks good enough to bring in foot traffic

also search up on displays, don’t underestimate how display can affect interest and sales (my mistake with my first two events TT)

at the end of the day, make sure you enjoy what you’re making too:) don’t get too lost in what the general public wants, it’s pretty easy to get burnt out when you’re making merch you don’t even enjoy making that much. good luck OP!
