When the clutch was replaced, I assume they either replaced or resurfaced the flywheel?
I wouldn't worry to much about it at this point it takes about 500 miles to fully break in a new clutch, according to some clutch manufacturers. A clutch smell is normal for a new clutch as it breaks in especially if you romp hard on it through first and second gear as it breaks in. You are supposed to take it easy for the first 500 miles .. again according to some manufacturers .
I would guess that if it burns up in 1000 miles you could take it back where you had it installed and get it covered under warranty.
Keep your foot off of the clutch when driving except when you shift. You don't need to let it out that slow when taking off, I cant explain how to do it you just have to practice. I been driving a stick for so long I don't even think about it.
