Hogue grips and the Apex spring kit are both good choices. I am pretty sure your Apex kit will offer three rebound spring options. I use the 14# in all my J-frames but many go lighter. I have never had any light strikes with any of the apex springs and they are in a good half dozen of my snubbies. I do not change firing pin springs or have need for a longer firing pin.
Using a correct screwdriver, get a good video and remove the sideplate. Lots of videos will show you how to smooth the the rebound slide in just a few minutes. Install your springs of choice, re-lube the insides, (I use a dry lube) and you should have a much smoother, lighter trigger. If you happen to get any light primer strikes just go up to the next wt. rebound slide spring. Unless, and even if, you have the correct rebound spring removal tool, do this in a clear plastic bag to prevent a long futile search for the missing spring.
