Problem is almost solved 
I’m new user and that (i think) was a major problem. When i made some changes it spent some time before someone (admin?) accept this modification (as i know new users are observed for a changes that they make) - so i guess the best way was wait some time to change take effect. Anyway, for now problem seems to be almost solved.
When it comes to tagging - “cmt” and “sym” are tags from gpx file. First i must to convert ESRI shapefile .shp which i had to Garmin Waypoints .gpx and only then i could load it to OSM as a trace. While conversion this tag was necessary…
Finally, i have 4068 points and it seems that i must manually edit every point, add some values and remove others. Maybe someone know any simplest solution to directly migrate from shapefile to osm?
Anyway, thanks a lot for any hints
