Only if you want that note to sound. If if it's intended to ring in the song. I think it's a good idea to be able to play it or not at will.

Question 2: Is my technique ok using my pinky instead of my ring finger? Thanks.

Yes, that's fine. Generally, any way that you can efficiently get a clean, clear tone from a note or chord is acceptable. Hope this helps!
