The best way to tag a changeset fpr review is to set the review_requested tag (as an attribute of the changeset). In JOSM there is a checkbox for that.
Your changeset seems OK.
For the speed limit, have in mind that not all data consumers uses or supports the maxspeed tag variants, so you may prefer to tag the default as 30, and 50 in the other times. It’s the same info about speeds and time, but tagged in a way that could be more useful.
