Welcome to FlyerTalk Jameswilson133!
I'm a physician seeing office patients and I use surgical mask, sometimes disposable gloves during the exam and it seems to work for me, so I'd think the Tyvek suit and N95 is overkill, not to mention very uncomfortable. I've worn plenty of regular clothing with metal zippers through the security check - no alarms. However there is quite a bit of variability - sometimes my boots set off the alarm, sometimes they don't.
