A slight RPM increase when shifting from "D" to neutral is normal. The reason for this is the engaged transmission is putting a slight load on the engine and slowing it down. In neutral the engine is ...

Going at 60-70 KPH in first gear - does it damage the transmission?

As long as you don't exceed the maximum speed (revs) of the engine you should be ok. If you do, then forces acting in the transmission can exceed design limits maybe causing damage.

My 2013 Nissan Versa has 176,000 miles and runs perfectly except when I go up a steep hill

My educated guess is its just getting up there in age and is starting to slip due to the added stress of having to go up hill. This would explain why it doesn't slip downhill as it is just coasting.
