So costwise to get everything it will take

9 Greens - All 3 trees
3 Greens - All Clothing
18 Greens - All Furniture
1 each Red/Blue/Yellow - Minion

There are 14 days of the event and you can get 3 per day from dailies, plus one green to start, so 43 fallen stars in total. If you want to get all the above items that will take 33 stars, so you will have 9 left to spend on Gift Bags and Food. If you don't have a house and don't want any of those items (note they are tradeable so you could them on the MW) you will have more stars to spend on the consumable items.

I wonder how the Gift Bags work. And what is inside each of them.

You can exchange 1 of the color ones for 2 green ones. The exchange is next to the vendor. So you can get 6 per day or 84 total green stars during the event.
