HELP:problems simplifying big matrices

I am a relative newcomer to mathematica. I wish to simplify large matrices by
identifying occurrences of specific algebraic expressions and replacing them
with a variable name. The problem is that unless the expressions to be
replaced occur in precisely the form specified by the given transformation
rule it doesn't spot them. Any simple solutions?
Also, is there any way to identify and collect vector powers (ie. v^2 instead of
v[1]^2+v[2]^2+v[3]^2 for example) ?
Thanks for any suggestions,
Stephen O'Sullivan.
