Everybody learns differently, so there is no single process that always works, but here are a few things to think about.
Pentatonics-
Everybody learns pentatonics at some point. However, they sit exactly on top of a major scale. If you're going to take the time to learn the different pentatonic positions, why not learn the major scale that is right there instead? it's easy to take away the four and the seven if you want a more bluesy sound, but you also have the option to include four and seven when you want more linear lines.
Another advantage of major scales is the 3-4 and 7 to 8 intervals that I just mentioned. They are the only half steps within a scale and are very easy to see when you're moving across the fretboard. It's much easier to see the half steps, to figure out where you're going, while pentatonics skip the half steps so you lose quite a bit of visual information.
Playing by ear-
This is crucial and can actually be very hard for classical guitarists and keyboardist who are not familiar with improvisation. So do it do it do it.
However, if you only play by ear, you can get in big trouble real quick. I think one of the earlier by ear examples was worship music where it's quite common to have modal progressions. A great classic example is All I Need with Danny Chambers and Lincoln Brewster.. incredibly talented musicians.
If you try to solo over this, or any similar song, you can easily be pulled into a trap that hurts the ears... The intro and chorus are in A, but the verse is lydian. As you would expect, it's written beautifully so you don't notice the transition...
But all of a sudden you have a d sharp where you were playing a d natural before and by the time you realize you screwed up, the next cord is coming and it's very hard to make it look like you knew what you were doing
Again, these are all different sides of the same coin. However when somebody already understands chord tones it can be a tremendous advantage to hook them together with scales.. pentatonics are pretty much automatic because they are simply a subset and you have the knowledge to avoid embarrassing notes when you add in the ear
