I will review our recent work on modeling cluster SZ number counts and power spectra, and the additional power due to scattering of the CMB by gas in filaments. Precise cosmological parameter extraction from CMB primary anisotropy necessitates reasonably accurate accounting for the combined anisotropy induced by clusters and filaments. I will disucss the levels of parameter bias due to the unavoidable residual signal from these structures.
