I know this problem. The possible solution is to use procsearch function if 
you know the name of method

set proc [$ob procsearch proc]

and ask the standard tcl info
if  {$proc!=""}  {
  info args $proc
}

To get all posible methods for some object in not so easy. I use something 
like that in XOTclIDE

Class instproc getAllInstMethods {} {
    set methods [[self] info instprocs]
    foreach class [[self] info heritage] {
	set methods [concat $methods [$class info instprocs]]
    }
    return [lsort -unique $methods]
}

You also must look for all mixins classes and procs methods
$object info mixin

Object instproc allAvailableMethods {} {
     ::set method {}
     foreach class [concat [[self] info class] [[self] info mixin]] {
           ::set method [concat $method [$class getAllInstMethods]]
     }
     ::set method [concat $method [[self] info procs]]
     return [lsort -unique $method]
}

There are also class mixins (not implemented above).

happy hacking
