You will need stabilizers, a good pair of curved little scissor snips, programs and a good machine embroidery book for referencing your projects for the best results. Check out your local library to see if they have a good one you think will be the best information before you buy one. That way you will know what you are getting. There are classes at our local quilt stores, maybe you could find one near you? Ours are now virtual, so no worries. I don't know how many bobbins came with your machine, but ordering extras might be prudent. And last but not least, a thread spool holder for those larger spools of thread that can save money on thread. My brother made me one and it makes all the difference.
One other tip, there are some people on utube that instruct on machine embroidery techniques. I am thinking some of the embroidery program sites also have tips and videos. Information and instruction is what you need to make it all go easy and be perfect when finished.
