@DangerDirtyD Got it. Multi tool, tube patch kit.
@Runs with Scissors Got it, getting the rear light.
@mtnbikej Got it!
Do you guys recommend a small little pack to attach to the bike to carry my stuff? By stuff I mean, multi tool, patch it, keys, ID. This one looks cool:

It's a matter of taste. I personally can't stand anything strapped to my bike. I used to ride with a seatbag, but that was before I had a full suspension bike.
Others would much prefer to put their stuff on the bike and not on their back. The latest "Enduro" trend is to wear an (
ahem) waist pack and carry a water bottle on the bike (and if you're super cool, to strap a spare tube onto your frame).
For most of the 2000s until about two years ago, hydration packs were de rigeur. Easy and clean access to water, a place for your stuff, and no extra crap on your bike. Hydration packs are now passe, apparently.
XC racer dudes (and dudesses) have NEVER worn hydration packs. They wear lycra shorts, tight jerseys with team logos and put their spare stuff in their rear jersey pockets like roadies. They are typically ill-equipped for problems, but hey, they nail their STRAVA times! Go KOM!!!
I usually use a Camelback or Osprey hydration pack with tools and, if necessary, a spare bit of clothing or pads. I do enjoy riding without a backpack when I can, and carrying some stuff in a stealth waist pack (hidden under my jersey) and a water bottle. Problem is, I can't carry a shock pump or put a jacket or pads in it. My little belt pack does carry my phone, a multi-tool, spare chain links, derailleur cable, some bandages, a clif bar, tire levers, tire bacon and a small tire pump. No tube.
Bottom line, do whatever you like.
(But the bag you are referencing seems like it would be highly annoying - noisy, unstable and in your way when you need to dismount on a steep uphill.)
