Linking Shape file with lat long points

I have a number of shape files using some form of projection that places the map at coordinates in the millions.
I also have tables that have lat longs that I have converted to shapefiles however they show up roughly at coordinates -115.0, 51.  This is because they have been based on their lat/long. 
I need these to line up with my shape files that are supposed to be at this location also.
I know this has something to do with the projections but when I attempt to alter the projections it tells me its not in decimal degrees and after playing around with it I havn't made any headway.
How can I syncronize these shape fiels so they use the same coordinate systems?
