The community had some notes on tools on the old Shapeoko wiki:

A nice ratcheting tool for a hex key helps a bit — I used a Silca T-Ratchet:

which is probably one of my most favourite tools (and which finally got me to stop searching for a vintage 1/4" Snap-on ratchet on the Extremely Big AuctionY site)
(I pair it w/ a nice set of 1/4" adapters/sockets/bits, including a set of Bondhus ball-nose bits)
Some folks put there machines on a sheet of foam — I did that and it helps deaden vibration and seems to dampen noise.
A nice set of flush cut pliers helps esp. if using lots of zip ties to arrange the cabling nicely:
Get a good quality pair of wrenches for collet changes (13mm low profile and 22mm stubby for the Standard Carbide Compact Router/Makita RT0701/0700)
Start w/ a level and begin by leveling the table — precision has to start somewhere.
A good quality square will help lining things up.
