First thing i'd be checking is that the clutch cable is excessively stretched, that could cause problems getting it into gear. On a similar level, check/renew the clutch pedal mechanism... if the ratchett teeth are screwed it wont self-adjust properly and cause similar issues.
As for the positioning of the gear level, that sounds like the selector fork is either bent or needs adjusting.
