Two questions:

1) Does LaTeX allow one to (re)define commands within a \newenvironment? I've tried using \renewcommand, \newcommand and \def in the before declaration but to no avail.

2)How would one redefine \item when creating a new list environment?

I've created a new type of list environment from scratch using \newenvironment while using another token instead of \item for each but I'd really like to keep things consistent by using \list and redefining \item.

Sure; it's hard to know what went wrong without seeing your code. As an answer to your two questions, see if this helps:

\documentclass{article}
\begin{document}
\newenvironment{myitemize}{%
  \begin{list}{}{}% whatever you want the list to be
  \let\olditem\item
  \renewcommand\item{\olditem ITEM: }
}{%
  \end{list}
}  
\begin{myitemize}
\item one \item two
\end{myitemize}
\end{document}

Thanks for the answer. I've tried it and succeeded but my original problem concerns parameters. I've asked another question.

Too late perhaps, but it may be useful for someone else

\newenvironment{coolitemize}{%
\let\olditem\item% 
\renewcommand\item[2][]{\olditem \textbf{##1}\\[0.3\baselineskip]##2}%
\begin{itemize}}{\end{itemize}%
}

and use it

\begin{coolitemize}
\item[Title of my first item] Text of my 1st item.
\item[Second one] And some text here.
\end{coolitemize}
