Dynamic Checkbox and Radio Group

You can't put any cf tag inside another one. In other words you can't do this

<cfinput <cfif>etc </cfif>>

But you can put cf tags inside html tags, like this:
<input <cfif>etc </cfif>>

i think CF form elements (like <cfinput>) do not like <cfif> loops inside of them... i remember i have tried it before and it didn't work... regular html form elements (i.e. <input>) are ok with it.
so i guess you will have to put your <cfinput> inside a <cfif>, like this:
(also, no need to use # inside cfif statements)

<cfif getLead.Request_for_Quote EQ 1>
<cfinput type="checkbox" name="Request_for_Quote" tabindex="22" checked="true"/>
<cfelse>
<cfinput type="checkbox" name="Request_for_Quote" tabindex="22" checked="true"/>
</cfif>
