  The resummation of multiple soft gluon emission affects the production rate
and kinematic distributions of $W^+h$ (where h is a Higgs boson) and $t \bar b$
pairs at the Tevatron with $\sqrt{s}=2$ TeV. Using the Collins-Soper-Sterman
resummation formalism, the production rate is enhanced over the
next-to-leading-order (NLO) prediction by 2-3% for the $W^+h$ process, for
Higgs boson masses between 80-120 GeV, and over 3% for the $t\bar b$ process
for $m_t=175$ GeV. After resummation, the $t\bar b$ rate changes by 12-13% when
$m_t$ is varied by $\pm 5$ GeV. Various kinematic distributions are presented
for the individual final state particles and for the pair. The explicit
radiation of hard gluons in NLO QCD is included also for the $t\bar b$ final
state.
