Couldn't find anything written up, and I'm not even sure how useful it will be, but thought I mite post up a step-by-step how-to on removing your dash surrounds, cluster, and centre control console.
The purpose for me doing this today, was I intended to install a B4 dash cluster to my wags, which was bought from a member here.
It didn't quite work out how I wanted it to, so instead I continued fiddling around and generally pulling everything apart and cleaning out all the gunk and crap that had accumulated in fiddly little places, like airvents!!!
Mods feel free to move or delete this, if it's not useful, or in the wrong area.
Tools Required:
Phillips screwdriver - Stubby shaft
Phillips screwdriver - Long shaft
Magnetic probe - a godsend for finding dropped screws
Clean work area
Good lighting
Time to waste
Patience
Beverages if desired

Remove negative battery terminal - there are plenty of times you will accidentally hit the horn, wiper or indicator stalks
Loosen the steering height adjustment lock, so the steering wheel can move up and down freely

Gently unscrew the gearknob until it comes loose from the stick.  The gearboot is permanently attached to the knob, but will free-spin against it allowing you to unscrew the knob.

Once free, gently prise free the gearboot surround - be careful not to break any of the retaining clips, or your surrounds will be loose and either rattle, or move, once reinstalled
Once removed, you can clean out the years of gunk that accumulates inside the creases and folds of the gearboot

Remove cigarette lighter - Remove ashtray

Using the stubby phillips screwdriver, remove the 2 screws inside the ashtray rails - they are hard to get to

Let the ashtray rail assembly dangle loose, or undo the wiring clip which is the ashtray light and remove the entire assembly
Remove the 2 screws which hold the bottom rubber dished tray in place - tilt it upwards at the rear of the dish, and slip it backwards.  There is a little plastic tab at the front edge directly under the cigarette lighter, which locates into a slot in the frame - be careful not to bust this tab off as you remove it

Gently prise off the surround on Right of steering wheel, where the cruise and foglight switches are from the bottom edge.  Be careful not to bust any of these clips too

The switches (or blanking plates) are removed by pushing through the FRONT of the panel, not the rear, so the harness clips must be unclipped to remove the panel fully.  My car has a security light installed which was hardwired to the immobiliser, so there was no plug to unclip, so I just let it dangle out of the way, as indicated in the photo

Gently prise around the centre console surround.  Most of the surround will unclip easily, but it is very tight and awkward at the top left, where the cup-holder pops out of the centre console.
It is easier to pop the cup-holder out, which will give you a bit better leverage when wiggling the surround loose of it's final few clips.
Be very careful not to twist or grab the cup-holder too much in case it breaks

Remove the 6 screws holding the centre control console in place - 2 on left of frame, 2 on right and 2 underneath

Gently pull the centrol control console out slightly, and let it rest in position.  At this point, you can unclip the plugs from the harness.
You can remove the screws on the side of the centre console frame, to remove each of the items in the DIN units.  I pulled out the open, and the flip-lid DIN pouches to clean them.
You cannot entirely remove the whole assembly unless you disconnect the sheathed cable for the heater unit on the fan control unit.  There is no picture to indicate this cable, however there is a single screw which holds a retaining clip in place.
There is no picture to indicate fully removing the stereo unit
Once it is free, remove the 2 wiring plugs for the cigarette lighter

Use the stubby screwdriver to remove the 2 screws on the inner top face of the dash cluster shroud
and the long screwdriver to remove the 2 screws from the bottom support braces of the dash surround
