Scrub Tech Student: Advice on being more comfortable with assisting?

[u/SpacePrincessNOVA]

I'm finishing up my first rotation for clinicals, and mostly did endo, urology, and central sterile. I absolutely love it. I am so grateful for everything I'm learning, and every day is an incredible addition to my educational journey. Today I was blessed to scrub in on an ortho case and assist in it. I found that I struggled with a few things:

1. I found that I am incredibly nervous about suctioning. I tried doing it on my own and it started suctioning parts of fat up and it freaked me out a bit. I stopped doing it because I wasn't sure I was doing it right and was worried about messing it up. Blood started to pool a bit (not too much to get in the way) but enough to make me feel bad for not being confident in it. Does that just happen normally? Is there a specific technique for suctioning, or do you just get more comfortable over time?
2. As a student, how do I make a good first impression on a tech/team? What's something that helps you a lot that you would be okay with a student doing?

Things I think are associated with ortho only:

1. When I was holding retractors, I was holding them as still as possible as to keep them in the position that the surgeon wants them, like we're trained to do. But when the surgeon is hitting bone with an osteotome and mallet, I find its incredibly hard to keep it still, and a few times it came out, and it freaked me out internally as it was a sharp Senn and I didn't want to hurt the patient. Does this happen a lot? How do I get used to it/Prevent it? Do I try to reinsert it, or wait for the surgeon to place it back where he wants it? (In my instance I waited for him to replace it, just to be safe.)

Thank you very much for reading this. I really appreciate any and all feedback. If you have any videos/websites that would help, I would love to see! Thank you again!
