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). PDF had done the conVersion, so you may want to check on the B5 Mod thread with him as well. Hope this helps
