PPG Sawdust is the closest matching paint I've found, but it's not an exact match. Please contact me if you've had the paint matched.
I believe Ibanez uses metric screws, however, Imperial sizes are close enough to generally be acceptable replacements.

Bill and Becky Wilde P-46 pickups are a direct drop-in upgrade. Most standard P pickups (Seymour Duncan Quarter Pound SPB-3, EMG, etc.) should also be a drop-in replacement.
EMG J pickups are available in at least two widths: 91.2mm (neck) and 94mm (bridge). I believe EMG PJ sets generally have a 94mm J pickup. The Ibanez Dynamix J pickup is 92.6mm wide. The TMBs pickup cavity may require a small amount of sanding when using a 94mm wide EMG pickup. Source: Climax, talkbass.com
Epic Custom Shop 92mm length J pickups require a small amount of sanding and new screw holes.
Gotoh VK1-18, VK1-19 knobs have 6mm smooth (no splines) shaft holes with a set screw and will fit the factory pot shaft.
Gotoh GB350 tuning machines are a drop-in replacement if the Gotoh ferrules (14mm outer diameter) are placed into the TMB factory ferrules, (14mm inner diameter) and a new screw mounting hole is drilled.
HipShot HB7 tuners have 18mm ferrules so the 17.5mm headstock holes will need minor sanding. The mounting plate of the tuning machines may slightly overlap, so one of the plates may need to be cut or sanded a bit. New screw mounting holes are required.

Hipshot Licensed 3/8" Ultralite Bass Tuning Machines have a shaft diameter of 13.75mm. Shimming around the shaft is required to prevent a sloppy fit. Wrapping about 9 inches of tape around the shaft will shim it to 14mm and they can be placed into the factory ferrules. However, the shaft will only enter the ferrule to a depth of 1mm, which will likely be adequate, but does not make me confident. As an alternative, a plastic or nylon bushing, sleeve bearing or spacer measuring 9/16" I.D. x 11/16" O.D. may be placed between the tuner shaft and the headstock hole. Unfortunately, I've had a difficult time finding a suitable bushing. I used Redline (Trailer Parts Pro) model SP05-020 (or SP05-040) bushings trimmed to a length of 8.5mm. The bushing required a few inches of tape around the outside to make a snug fit into the headstock hole. The tuner shaft required a few inches of tape to make a snug fit in the bushing. A new screw mounting hole is required. Although these tuners can be made to fit, I personally do not recommend using them in the TMBs. The Gotoh GB350 tuning machines offer a much easier fit. Please contact me if you have a good solution.
Hipshot USA 1/2" Ultralite Bass Tuning Machines require a 17mm or 17.5mm hole. They may be used with the factory ferrules with a small about of tape around the posts to shim. New mounting holes are probably needed. Source: Blues Bass 2, talkbass.com, bigthemat, talkbass.com
Hipshot USA 3/8" Ultralite Bass Tuning Machines require a 14mm hole and may be a drop-in replacement with possible shimming and with a new screw mounting hole. (Unverified)
Jack plate model JP-CST-C (chrome), JP-CST-B (black) are drop-in replacements.
The Gotoh 201B-4 bridge has 17.5mm mounting hole spacing and is a drop in replacement for old style bridges.
The Hipshot KickAss bridge has 17.8mm between mounting holes. The old style bridge has 17.5mm between mounting holes. The difference is small enough that you can mount a kickass bridge using the factory holes without too much trouble, but the outer screws may be a bit tilted. The new style bridges have a completly different mounting hole pattern, so new holes will need to be drilled.

Pots made by Taiwan Alpha with a "K Type" 6mm knurled shaft will fit the factory knobs and Gotoh VK1-18, VK1-19 knobs. The "R Type" smooth shaft has a 6.3mm diameter and will not fit. Pots should have a threaded shaft diameter of M9 (8.9mm). Pots mounted in the jack plate should have a threaded section (bushing) at least 6mm long. Pots mounted in the pickguard should have a threaded shaft section at least 5mm long. Some pots have imperial or standard sized threaded shafts with a diameter of about 3/8" (0.38"), e.g. CTS, but the TMB pickguard pot holes are only 0.35" (8.9mm) diameter. Metric pots with a threaded shaft diameter of 0.3" (7.7mm) are drop in replacements. Credit: ThumpingJack, talkbass.com
