  We combine the constraints from the recent Ly-alpha forest and bias analysis
of the SDSS with previous constraints from SDSS galaxy clustering, the latest
supernovae, and WMAP . Combining WMAP and the lya we find for the primordial
slope n_s=0.98\pm 0.02. We see no evidence of running, dn/d\ln k=-0.003\pm
0.010, a factor of 3 improvement over previous constraints. We also find no
evidence of tensors, r<0.36 (95% c.l.). A positive correlation between tensors
and primordial slope disfavors chaotic inflation type models with steep slopes:
V \propto \phi^4 is outside the 3-sigma contour. For the amplitude we find
sigma_8=0.90\pm 0.03 from the lyaf and WMAP alone. We find no evidence of
neutrino mass: for the case of 3 massive neutrino families with an inflationary
prior, \sum m_{\nu}<0.42eV and the mass of lightest neutrino is m_1<0.13eV at
95% c.l. For the 3 massless + 1 massive neutrino case we find m_{\nu}<0.79eV
for the massive neutrino, excluding at 95% c.l. all neutrino mass solutions
compatible with the LSND results. We explore dark energy constraints in models
with a fairly general time dependence of dark energy equation of state, finding
Omega_lambda=0.72\pm 0.02, w(z=0.3)=-0.98^{+0.10}_{-0.12}, the latter changing
to w(z=0.3)=-0.92^{+0.09}_{-0.10} if tensors are allowed. We find no evidence
for variation of the equation of state with redshift,
w(z=1)=-1.03^{+0.21}_{-0.28}. These results rely on the current understanding
of the lyaf and other probes, which need to be explored further both
observationally and theoretically, but extensive tests reveal no evidence of
inconsistency among different data sets used here.
