Yep, the Monorail was already there, as was the land, for the GF since it had been reserved for the Asian Resort. Floridian Way was still called Asian Way until the GF was built. I recall the Monorail shuttling whilst the station at the GF was being built.
Interesting tid bit - the Golf Resort wasn`t meant to be a resort. It was originally a large club house for the Palm and Magnolia courses, but so many golfers wanted to stay `on course` they added rooms and hotel infrastructure, hence the name.
Here is the newly opened resort - the bottom half is the new addition, the top half the original club house. Notice the space for the Asian / GF too.
The village resort was the original community for WDW. It was to have been built in tandem with E.P.C.O.T. As EPCOT moved from city to park Lake Buena Vista Village was to have been WDWs main residential resort, but as it was buiilt through the 70`s became an executive getaway and then a guest resort. The Village was originally to be the shopping village for residents as well as guests, the Sun Bank building was the first of a proposed 13 office blocks, a 600 acre expansion was to have been built along the eastern border - project 50 with 900 apartments - a downtown complex with a highrise tower would have been built as the center of LBV and the whole south east area serviced by a WEDway linked to the eastern Monorail spur.
