Mark your table with a little dot (sharpie marker or similar) at every diamond intersection. You won't notice them when playing. If that's not precise enough for you, make a mark with a turned down chalk where you want to setup your balls. These can be brushed/vacuumed away if you'd like. The adhesive 'paper hole re-inforcer donuts' work good too, but they're a bit of a hastle and you'd probably won't want to actually play with them on your table (never tried transparent ones).
The objective is to improve your game, regardless. Whatever it takes - enjoy the journey. There's a lot of great info on this forum at your disposal, just search it up. I'm always finding things about stroke, grip, bridge, etc., that are helpful. There's some very qualified contributors sharing their 'secrets'.
A lesson with a SPF guy is the way to start (I did and my game is far better now because of it).
