LST

Your aim ATM should be to keep doing the lst so that all tips are at the same height/canopy. If outdoors them maybe not relevant. In regards to removing fan leaves. It's fine as long as a few checks are done. If a leaf lower can use that light and is there enough growth from the connecting leaf above itself. Are you in veg is another check. Unless it's an auto id recommend topping it very soon.

Just leave them on in my opinion the more leaves you leave alone the better the means the plant has to make big buds
