First Crabapple

This is a Zumi crabapple I got last year. I have very little deciduous experience so I’m curious if any of you may have some pointers. First, I want to know if this is sufficient movement for the first stage of growing. I don’t want this to look like a tornado, but I also know that as it thickens these curves will soften, so I’m not sure if I need to go more extreme or leave it as is. I’m also curious if the wire bite is ok, on my junipers I would consider this negligible, but I’ve heard that wire bite on some deciduous can be permanent even if it’s relatively shallow. Then I would like to know if I should leave the two suckers to thicken the base and lastly I was told on a post in the last to plant it in something broad and shallow. Would it be best to repot this spring into straight organic soil on a bigger pot, or will this suffice for another year or two? I probably should have put it in a pond basket to let its roots escape, but I may be moving stated this year so I don’t think I can start that confidently this year.
