The recent discovery of high-temperature superconductivity (HTSC) in dopedIron pnictides is the latest example of unanticipated behavior exhibited by$d$- and $f$-band materials. The symmetry of the SC gap, along with themechanism of its emergence from the ``normal'' state is a central issue in thiscontext. Here, motivated by a host of experimental signatures suggesting strongcorrelations in the Fe-pnictides, we undertake a detailed study of their normalstate. Focussing on symmetry-unbroken phases, we use the correlated bandstructure method, LDA+DMFT, to study the one-particle responses of both ${\rmLaO_{1-x}FeAsF_{x}}$ and ${\rm SmO_{1-x}FeAsF_{x}}$ in detail. Basing ourselveson excellent quantitative agreement between LDA+DMFT and key experimentsprobing the one-particle responses, we extend our study, undertaking the firstdetailed study of their normal state electrodynamic response. In particular, wepropose that near-total normal state incoherence, resulting from strong, {\itlocal} correlations in the Fe $d$-shell in Fe-pnictides, underpins theincoherent normal state transport found in these materials, and discuss thespecific electronic mechanisms leading to such behavior. We also discuss theimplications of our work for the multi-band nature of the SC by studying thepairing ``glue'' function, which we find to be an overdamped, electroniccontinuum. Similarities and differences between cuprates and Fe-pnictides arealso touched upon. Our study supports the view that SC in Fe-pnictides arisesfrom a bad metallic, incoherent ``normal'' state that is proximate to a Mottinsulator.
