You may have to remove some of the trigger to slide it out but I'm not sure since I'm not in the mood to take mine apart. I don't think you do. Make sure to do a good function check when you're done.
As for brands you can get a JP that is awesome but pricey or Stag which is iffy. I have one that is tight and smooth but my other one is wobbly and not so great. They were reasonably priced and do their job, though.
As for other stuff, you can get ambi mag release AND a charging handle to lefty it up more. I have a Norgon ambi catch for my mag release and the handle is by Armadynamics. They run about $90 a piece so I'm not sure if you want to spend that on a .22 but they are both quality parts. For a lefty who really runs their rifle they're must-haves along with a safety selector.
