Questions as a MS3/soon-to-be 4th year student

Hey yallll US IMG student here. I got some questions that have been on my mind and I want to see what you guys think!

I'm almost done with my third year core rotations then gonna start my first elective in anesthesia<3

1) Do you guys think it's a big deal if I do all my electives at the same site I did all my cores? I'm comfortable there, but they don't have an anesthesia residency program. I can still get LORs from the anesthesiologists when I do my elective (specifically the department head) but liike is it a big deal, how will that look to the programs I apply to? Better to get strong letters from people who know you right?

2) My school requires our sub-I be done in a core specialty so I'm thinking psych because I enjoy it, but not necessarily going to request a letter. Will that look weird? Should I do it in IM? Not too pressed about an IM letter because I figure my letters will be 1-2 anesthesia, 1 family medicine, 1 ICU (maybe will ask for a letter from surgery core depending on how it goes) and of course the MSPE

3) Wild card question but has anyone heard of or had experience with a Step 2 tutor? I want to secure anesthesia as best I can and I think we can all agree a Step 2 score +240 is the way to tackle that and if a tutor can help "guarantee" that then I'm downski

Thank you in advance for taking time away from UWorld to answer and help me out haha
