Okay.
Let's take this one step at a time.
You are having problems getting Reaper to load VSTfx and VSTi plugins.
The very first thing you need to do is hit Control + P. A 'Reaper Preferences' screen pops up. There is a list on the right side, and you want 'Plug-ins' and the sub head 'VST'. There you can type in C:\Program Files\Steinberg\VSTPlugins. That should solve your first problem.
Reaper calls all plugins 'FX'. To place one in a track, click on the gray 'FX' in the track bar. This will bring up a list of all the plugins in the folder you've designated in 'Preferences'.
