Welcome to the game murek. You have a good approach in coming here and asking questions, many new players simply get discouraged, never seek advice and never learn the game (or worse, learn the game improperly). The advice you've been given so far is all good, the only thing I might add is something regarding landing. You said you have trouble lining up and actually touching down on the runway. This is where rudder is very useful. Use rudder to make minor course corrections and you will not need to take the time to roll one way or the other. Rudder also creates drag, which bleeds off excess airspeed, which can also help you in getting slow enough to land.
Remember when landing, if you think you are slow enough and still flying, you can always get slower. The easiest landings are actually controlled stalls: the plane stalls just as the wheels are touching down. If you land as slow as possible (use flaps), and try when possible to use "3 point" landings (centerline wheels and tailwheel touch at the same time), your landings should not be any issue at all. Just takes patience, and practice. Good luck.
