About your dash...here is a link that describes what I did to paint a new OEM gray dash brown (pages 2 & 3 of thread). You can get it for $510 with free shipping (Coupon code: FREESHIP ) from Parts at Passport Toyota.com: SEM Paint and supplies will cost you another $60 and 6-8 hrs labor.
How to Change FJ62 Dash Color
Pad sub-assembly, instrument panel safety. Shadow gray. 1988 Toyota Land Cruiser. Genuine Toyota Part - 5540190A0503 (55401-90A05-03, 5540190A0505, 5540190A0703, 5540190A0705). Ships from Passport Toyota, Suitland MD

If you do have access to a reasonably-priced and gifted upholsterer you might be able to get something close to OEM for the same price.
I contacted Just Dashes and the cost was closer to $1200 (not including shipping).
For sound deadening, I bought two 36 ft2 boxes of the Noico 80 mm butyl and topped it with the 157 mm Siles closed-cell foam (another two boxes). There was enough of the Noico left over to do the inside of the doors, but not the rear quarters. Along with new door seals that will make a big difference.
Eventually you'll want to buy my stickers made for the 1988 FJ62 for $65:

And...if you haven't already done so, buy the two bushings for you transmission shifter handle and a new bulb while you are in there. Only a couple of bucks.
Finally, to answer your question I only know that the best match for the dash color is SEM Cordovan Brown. The other shades of brown are a mystery, but I can tell you for sure it isn't the same brown currently on your E-brake shifter.
