What you have downloaded so far is correct, but since you are playing with GOLD, there is one more file you need to download and install to make the mod 'GOLD'.
B5 Gold Data Files
This will replace many of the files from the 1.49 Version (at least the ones you need to replace for Gold).
The 'complete' mod has yet to be posted in one zip. The goal is to have 1 'Core' file that will have all the files in common for both Mods (Classic SE IV and SE IV GOLD) then to have a data file for either classic or gold.
Hope this helps
