I like the $10 Taylor Digital Instant read thermometer also. A probe thermometer is also indispensable, remote is nice but the polder will work fine also. You can't have too many thermometers. I have one in the lid, an instant read digital taylor and a polder.
I didn't at first but I now use a lot of the disposable gloves.
I also recommend a large cookie sheet/jelly roll pan. If I am not mistaken cookie sheets don't always have the lip and jelly roll pan's do. Get one with a lip to hold the drippings.
Also get the warehouse size wide aluminum foil. I use a lot.
