Yeah it's me and I'm in love again,

Received my first revolver this past week and spent some quality time with it at the range yesterday. I fear .357 may have ruined me for 9mm, oh well. Couple of questions for the revolver fans out there. I may have to adjust the rear sights and would prefer not to use the trial and error method, anyone know what way turning the screw will move the poi?
Two of the screws holding the side plate on are slightly damaged, looks like someone used the wrong size of screwdriver to remove them and left sharp edges on the screws, where might I find replacements?
The thumb piece that releases the cylinder is a little loose, is this normal or should I tighten the screw?
Lastly I'm wondering if I should remove the side plate to inspect, clean or lube the inner workings?
Thanks for sharing your knowledge with a new wheel gun fan.
