how to set arguments for views ?

drupal 5.x and view 5.x1.6
If I have this menus

VOCABULARY A (category/19)
Term1 (category/19/65)
-subA (category/19/65/66)
-subB (category/19/65/67)
-subBB (category/19/65/67/70)
Term2 (category/19/64)

VOCABULARY B (category/1)
Term1 (category/1/27)
Term2 (category/1/28)

For to use views, instead of default list visualization, I have settings this:
view 01) for vocabulary A
URL:category/$arg
argument Taxonomy: Vocabulary ID

view 02) for term1 (and the others terms 1st level)
URL:category/$arg/$arg
argument Taxonomy: Vocabulary ID
argument Taxonomy: Term ID

question n1:
for every subcategory of terms I must to create own view?
in the situation above for subA must to do a new view 03) with URL:category/$arg/$arg/$arg

and for subBB a new view 04) with URL:category/$arg/$arg/$arg/$arg
or is there a tips?

question n2:
for to have the views applied only for vocabulary A or its terms and not if click
on vocabulary B or its terms; whic is solution? special filter or other?

question n3:
in the Title is possible to have the name of the term selected?
I tested $arg, %, %1 with Argument Taxonomy:Term Name
but not work;
