First thing is first. Make sure you set your K-50 to shoot in RAW & JPEG. You'll be able to use the jpegs as reference when you are post processing whatever RAWs you like the most. More than likely you will need to process the high ISO raw files with Lightroom, RawTherapee, or whatever you use to get a clean picture. I use RawTherapee since it's free.
If you're comfortable shooting with the "M" dial (manual), this would be your best bet. You can set the shutter speed, aperture, & ISO as you need it. You can leave the focus in AF.S. There are times when the K-50 struggles to autofocus or can't even focus in low light. That's where you'll have to flip the switch to MF & focus the shot yourself.
You can set the ISO in each dial to shoot from ISO 100 to ISO 3200 & let the camera figure out the settings. You can shoot up to ISO 3200 & then post process the RAW to get a clean picture. The grain (luminance) & color noise starts getting pretty rough at ISO 6400. I rarely shoot that high, but in a tight pinch, it's still usable for an 11x14 sized print after post processing the RAW file. Maybe even a 16x20 print, depending on the shot. You won't be able to get that size from the out of camera jpeg. Too mushy & grainy at that point.
Get a flash for sure if you plan on using the slower lenses & need to catch some action. The small & lightweight Pentax AF201FG should work fine, but there are a ton of other ones too. You'll have to do some reading 'cause there are too many options that can also include wireless flashes & stuff.
