Yes I think 2 point is smallest line and font sizes shouldn’t be too small either (I think about 9? but cant remember)
Illustrator has an awesome trace tool (converts raster to vector), and its as easy as ‘placing’ (file/place) the image you wish to trace in an new document click on the ‘live trace’ button (which appears in the small menu palate along the top under the major menus (file,edit,object etc)
REALLY useful for vectorizing hand drawn illustrations and all sorts of things off the internet. works best with high res images but can be useful for low res as well. I’m not a fine art illustrator unfortunately, so it really comes in handy.
Youtube has some good videos but the suite comes with a fair ‘Get started’ turorial if you have the time to study it.
Good luck!
