Yes you can, in the daily quest for shards... that's farming, then doing the basic tier 3 one to sell them... that's farming
No you can't - Class 5 Basic Catalysts are not available yet. (you may be confused with T4B) So there is no way to farm them at this time. But saving your T4B and selling them in the future is a way to go about farming them when they do release them.
