John, I have not yet built mine, but I am planning on using Tamiya's prescribed paints.
I have done a 43rd in a dark blue, think it was TS54 or something like that - sorry, this is from memory, TS89 was not yet available. Looks good in the scale and in 43rd, the decals really liven up the paint.
Likewise, for the yellow I'd stick to their prescribed yellow - whether it's TS16 or TS47, since it will most likely match the decal sheet for other yellow bits. Unless, of course you plan to do all the yellow yourself.
Will look at some other opinions and build and come back to you later.
