Is ppm really important for growing in soil? Do i have to adjust this at all? My tap water ppm is normally around 50

Of course ppm levels matter my friend. Unless you want to lock out your plants you need to keep your levels in check. If your ppm level is to high, you can burn your plants and lock them up. Your reading of 50 ppm is perfect for growing. Anything over 150 is a high level that would may want to avoid. R/O would be the simple easy fix for levels to high.Depending on what nutrients you pick, you might not even go over 1,000 ppm's your entire grow. I never go over 1,600 ppm's in flower myself.

Anyways, your water source is good to good.
 
As long as you are under ~150ppm, and the PH is 6.3-6.8 you should be able to use your tap water yes. Now obviously you need to make sure there are proper amounts of iron and chlorine are in control as well.

My ph is between 6.5 and 7 and i usually let the water sit out for a few days before i water for the chlorine to evaporate as they say. I have no idea about the iron is it safe to skip the iron stuff? And how can i test for it if not?

when you make your pots up
add dolimite lime / garden lime follow directions on bag <~~~ this keeps your ph in check and gets rid of those nasty cal-mag issues
you can let your water sit overnight to get rid of the chlorine
