First, let me say that your subscription will not allow you to add more points to your web map. A subscription will allow you to create a feature service that can serve up those features rather than storing them in the web map. So, if you are able to load the 1000 features via drag-n-drop and get acceptable performance, then you are ok. The 1000 feature limit is a general guideline and will vary depending on the type of features (points, lines, polys) and the browser you are displaying the web map in.
Now, about the text coming across differently, are there addresses in your CSV file? Can you share your CSV file here?
Thanks,
Mike
