meta description is still usefull,
when google lists your page, it can use this description in the “snippet”, that is the description below your url in the searchresultspages, if you write it well, it can attract people to click on your link
not top in your source – not very important
description and title must be different for every page
freeboard or a simple webpage with a shorter URL- not much difference imho
have fun building your new webpage!!
