Gilded Goose Sacs a food token for a mana. If I have a Trail of Crumbs do I get the mana before the ability triggers, IE can I use the goose's mana to pay the 1 for Trail?
I'm assuming yes since mana abilities don't use the stack and just "happen" but just want to be sure.

Vraska, Golgari Queen uses +2 ability to sac a food, draw a card and gain a life. If I have mana and choose to pay the Trail of crumbs ability, which effect happens first? I'm assuming Trail ability resolves first, but I'm not 100%. Vraska might sacrifice and draw upon resolution. I'm a little unsure of those types of abilities.
