After an assessment of systematic errors in present simulations, results for the B meson decay constant, the B-parameter B_B and semi-leptonic heavy-to-light and heavy-to-heavy transitions are discussed. The final topic are lattice results for heavy baryon spectroscopy.Invited talk presented at the III German-Russian Workshop "Heavy Quark Physics", Dubna, Russia, 20-22 May 1996. 8 pages, uuencoded, gzipped tar file containing LaTeX source and style fileHigh Energy Physics - PhenomenologyHigh Energy Physics - Latticetext
