Can I use a 89-91 (S5) tail light on my 86-88 (S4)?
Yes with minor modifications to the body of the 86-88.
Here is a link on converting: http://www.aaroncake.net/RX-7/taillights.htm

Will 89-91 (S5) mouldings or bumpers fit on my 86-88 (S4) RX-7?
other than some minor mounting hole differences on the front bumpers, the mouldings and bumpers will fit fine.

What size are my wheels?
The stock sizes all have an offset of 40mm or 40 ET and are:
14x5.5 (steel) w/114.3x4 bolt pattern (Base)
14x5.5 w/ 114.3x4 bolt pattern (Base, Luxury, 87.5-88 SE)
15x6 w/ 114.3x5 bolt pattern (GXL, Sport, GTU, 91 coupe)
15x6.5 w/ 114.3x5 bolt pattern (convertible)
16x7 w/ 114.3x5 bolt pattern (Turbo, GTUs, Infini IV)

In addition please see below in this thread for stock wheel type and weight.

On the same vein, the stock tire sizes are:
14x5.5 = 185/70HR14
15x6 & 15x6.5 = 205/60VR15
16x7 = 205/55VR16

Will 3rd Gen RX-7 (FD) wheels fit on my 2nd Gen RX-7?
If you have 5 lug hubs and use spacers. Typically you need spacers around 25mm (1"), depending on tires

I want to change my wheels to something bigger. What offset should I use???
