The rotation curves, velocity dispersion profiles, and the H3 and H4 coefficients of the Hermite decomposition of the line-of-sight velocity distribution are derived. The radial profiles of the Hβ, Mg, and Fe line strength indices are measured too. In addition, the surface photometry of the central regions of a subsample of four galaxies recently obtained with the Hubble Space Telescope is presented. The data will be used to construct dynamical models of the galaxies and study their stellar populations. Description: The sample of E and S0 galaxies of the Coma Cluster is presented in the first paper of the series (Mehlert et al., 2000, Cat. J/A+AS/141/449). Long-slit spectroscopic data of the sample galaxies were obtained with the 9.2m Hobby-Eberly Telescope (HET) at McDonald Observatory, Texas, and with the 2.4m Hiltner telescope of the MDM Observatory at Kitt Peak, Arizona, during different runs between 2002 and 2005. The galaxies GMP 0756, GMP 1176, GMP 1990, and GMP2440 were observed with Wide Field Planetary Camera 2 (WFPC2) on board the HST on 2007 April 18-24. File Summary:
