I use slim as login-manager which is GuixSD's default.  I modified the
xorg-configuration in my system-configuration like this:

        #:startx (xorg-start-command
            #:configuration-file (xorg-configuration-file
                #:extra-config (list
                    ;; touchpad
                    "Section \"InputClass\""
                    "  Identifier \"touchpad catchall\""
                    "  Driver \"synaptics\""
                    "  MatchIsTouchpad \"on\""
                    "  Option \"MaxTapMove\" \"231\""
                    ;; natural scrolling
                    "  Option \"VertScrollDelta\" \"-200\""
                    "  Option \"HorizScrollDelta\" \"-200\""
                    "  Option \"HorizTwoFingerScroll\" \"1\""
                    "  Option \"TouchpadOff\" \"0\""
                    "  Option \"TapButton1\" \"1\""
                    "  Option \"TapButton2\" \"2\""

Yes. Use the GUIX_PACKAGE_PATH variable which is documented in the
manual, in chapter 6.6:

Good luck!
