  The purpose of this paper is to collect and make explicit the results of
Langlands, Bump, Miyazaki and Manabe, Ishii and Oda for the $GL(3)$ Eisenstein
series and Whittaker functions which are non-trivial on $SO(3,\mathbb{R})$. The
final goal for the series of papers is a complete and completely explicit
spectral expansion for $L^2(SL(3,\mathbb{Z})\backslash SL(3,\mathbb{R}))$ in
the style of Duke, Friedlander and Iwaniec's paper on Artin L-functions. We
derive a number of new results on the Whittaker functions and Eisenstein
series, and give new, concrete proofs of the functional equations and spectral
expansion in place of the general constructions of Langlands.
