    Old tub with or without fresh glue as a spare?

    Don't bother with fresh glue unless it was a track mastic-- shellac based or other non-sticky cement. Rim heat and pressure (from inflation) will be enough to create a sufficient bond to get you home.

    Do you pre-glue a new tub to carry and use as a spare?

    Don't use a new tub as spare. Best are old repaired tyres.

    Brush off the old loose mastic bits with a stiff brush. Add a thin layer of fresh mastic and let dry.

    will now have diesel powered black cabs? The drivers of which are actively anti-cycling?

    Not explicitly anticycling but aggressive to all other competitors for the route ahead. Luckily they're highly trained drivers.
    Imagine opening the trade to literally anyone-- the final consequences of Uber and friends-- while increasing driver competition and the pressures to push through and get a good review.. they have little choice once they join ranks.. little pawns on the board which will inevitably be replaced by robots and left in debt..
    The clock for The black cab too is ticking but as one of the pillars of public transport they won't just disappear but will clearly see their functional duties shift and evolve.

    How many track bikes are drilled for a rear brake! Those clamp on dia compe things are so ugly as well.

    They work, however, relatively well and are fast to remove should you also use the bike at the velodome. Solutions for the front-- especially if your fork does not fit into any of the 3 standard types supported by the DiaComp solution-- are generally less flexible and more problematic but required if you use a freewheel..

    German StVO (highway code) is mental.

    You might have to also fit reflectors, dynamo/lights etc etc to comply.

    They have changed the laws. Battery lights are no longer reserved for sub-11 kg bicycles. Reflectors? Police tend not to be terribly stringent on enforcing reflectors but reflective sidewall tyres or even reflective rim tape do meet the requirement. The fine for missing reflectors or a bell is also relatively modest-- I think now 10 or 20 EUROs.

    The law does require 2 independent working brakes-- "Fahrräder müssen 2 voneinander unabhängige Bremsen haben"-- but gives a lot of leeway into what constitutes "working". Courts have rulled that a fixed gear is a brake. This means that a single rear brake or front brake is all that is required. The law does not stipulate which but only demands redundance-- a chain or cable can, afterall, fail.

    wondering if black felt-tipping them first will affect the glue

    Old school markers contained toluene or other solvents that could effect the cement bond between basetape and tyre. This is your main concern and the limiting factor of the tyre-rim bond.

    Which brand / manufacturer produce the absolute top end sealed pedal bearings? I would also prefer to source from UK manufacturer.

    Top-end and sealed don't combine. Which bearings fit your pedal depends, of course, on the pedal model. Since I assume you have cartridge bearings I'll talk about them-- with cup and cone you just purchase good quality balls from the same lot. Highest performance are typically shielded-- or even fully unsealed. The "Gold Standard" are high grade ceramics-- cheap, inexpensive ceramic cartridges tend to be inferior to similarly priced steel bearings-- but they are also quite expensive and not really of use beyond placebo. Speedplay uses 686 (13x6x5mm) outer and 137 inner (13x7x4mm). These are industrial products and best purchased from an industrial bearing supply-- where the bicycle companies also source them. SKF (Swedish) and EZO (Japanese) are quite well known and established makers but there are a number of other suppliers such as Schaeffler Group (FAG and INA) in Germany that also produce extremely high quality and well regarded bearings.

    Lyft-- recall GM funding ($500M investment in 2016 which amounts to around 1/4 of the total money they have raised) for just this purpose-- has now launched Level5:
