If so, does anyone know of a different way to get user input from my web page to be accepted as the first argument in contains()? If more detail is needed to answer this question, please let me know.

"Variables in XSLT are not macros!" (c) xsl-list. When you have a 
variable holding string, it's just string, no matter what is inside the 
string and you can't expect this string will be magically interpreted as 
XPath expression.
In your case there is a workaround though:
<xsl:for-each select="doclist/doc[contains(*[name()=$param1],$param2)]">
