I recommend reading and developing, honestly, based on your own stylistic leanings and techniques. Last but not least, if you're interested in some different brushes, check out the Frenden brush pack, which has some really fantastic tools, some I'd even call indispensable! Since brushes are super-easy to add to Manga Studio 5/Clip Studio Paint, I'm sure you'll have no trouble and these new tools are really fantastic with the program.

Watch all of the Clip Studio Paint/Manga Studio 5 tutorial videos by Doug Hill, because they'll give you a great command of the program! It also has the ability to reset all the tool settings to what they were at the start, which makes it a lot easier and less stressful to just play to your heart's content with settings! Don't be afraid to experiment with pressure levels, technique, and more - it's the one thing that really opened up my ability with paint, such as it is!

I also recommend tweaking the brushes to what you are more comfortable with. I've watched countless ones that turned up with those searches! Do some searches for Clip Studio Paint and speedpaint, or tutorial, or process. There are a bunch of videos on youtube, though I'm not sure how useful each of them will be to you, but you can probably find at least some that will speak to you in their process.
