Practice over and over, make sure you have the parts down really good. Any pre-production can be good as well, even a shitty one mic recording can be helpful in making sure the parts are sounding good together. Practice with a click track, it will sound tighter and make overdubs a lot easier.
Get new guitar strings and drum heads but break them in a day before, you want them to be stretched and staying in tune. Make sure the kit is in tune, if you can’t do it find someone that can. Intonate your guitars and make sure cords and amps aren’t causing any buzzing.
Singers should do some good warmups and stay away from milk or anything that causes a lot of mucus. I like to book singing sessions later in the day to give the singers voice time to get ready.
Stay calm, the better prepared you are the easier it will be.
