As Denti pointed out. I know a couple guys and gals with tats, some rather impressive body ones at that. Just make sure they're covered. In fact, my current outfit has a policy about it in our Ops Manual that states just that, the tattoo must be hidden from view.
As for your training questions, go to the Canada forum and repost there - you'll get more "Canada specific" answers which, in the training world, is really needed considering how different every country does ab initio training.
