My question is should I really do this memorisation and playback or should I concentrate on trying to feel the patterns and scales associated with the chords?
I guess my question really is as a beginner will it all gel at some point down the line or should I put the more tedious work in now on making sure I understand why the notes are written along with each chord.

You do both. Put in all the tedious technical work now and work on being able to "feel" at the same time. You also have to change your focus and thinking so you're not a guitarist playing bass but a bass player.
Many if us start out having to learn everything at once. we have to learn how to make music, how to play an instrument and how to play with others. Surely as an experienced guitarist, you've already done the groundwork. Playing with other musicians, the music, notes, chords, modes, scales and timing doesn't change. Now you just have to adapt what you already know and how you play it and expand on it as a bass player.
