The first, Metaplectic Eisenstein Series on GL(3) contains two articles with more details about some of the proofs. The second, Gelfand-Tsetlin interpretation of Chinta's A5 polynomial is only available as a TeX dvi file since this is a smaller format than postscript or pdf. You should not print it since it is very long.
