We describe two measurements using 110 +/- 7 pb^-1 of data
collected by the CDF detector during 1992-95.  The first is a new measurement
of the charge asymmetry in the lepton rapidity range 0 < |y_l| < 2.5 using W
-> mu nu, e nu events.  The asymmetry data constrain the ratio of d and u
quark momentum distributions in the proton over the x range of 0.006 to 0.34
at Q^2 \approx M^2_W.  Although the data in the central rapidity region
(|y_l|) < 1.1) are reproduced by modern parametrizations of parton
distributions, there are differences in the high rapidity regions.  The second
measurement is a direct measurement of the W width using the lineshape of the
transverse mass spectrum.  The extracted W width is in good agreement with the
standard model value, and with values obtained from the indirect method using
the measured ratio fo W and Z events.
