Ventilation is recommended because you don’t want to be breathing in toxic fumes. Not everything that is odorless is harmless.

Definitely cover. There will be overspray. It goes farther than you would guess!!!

I use Elmers wasable school glue, last quilt I did was 112×112. It worked great was easy to FMQ through and washes out. Bought it at Walmart for $10.98 a gallon.

I too use washable school glue. It's economical and tidy. Hold the bottle about 6-8 inches above the batting so you get a thin stream and move the stream in a zig zag fashion. It will bead up. You don't need much. Smooth the backing over the batting with your hand. Let dry. Flip over and repeat for the top. Put the glue on the batting and not the fabric so it doesn't soak through. Wash quilt with warm water to get the glue out.

I use Dritz and 505 and don't have a preference...both work well. I do not do an all over spray but spray spots like you would if you were using safety pins. Saves money and works just as well. I lay out a sheet still but it's not a lot of spraying...just enough to tack down. I let sit for an hour then, sew... No gumming issues...

I just found a quilt store/sewing machine dealer near me that carries the big cans. Woohoo! I don't like the little cans because if I'm basting a big quilt I go thru them so fast
