Hi Sal2...

1. You cannot use any of the modeling tools during animation. You can try
the
various deformers or blendshapes, which is the normal method for more
complex
objects. Or for a simply extursion have an identical shape as your
finished
extrusion and move or scale the simply poly out of the object with time
(using
either the graph editor, set keys in the time line or both).

2.You can switch the textures during animation in a number of methods,
such as
using the conditional node or the color blend nodes in hypershade.

---- Using color blending (simplest to explain). In the hypershade...
a. Select a material (blinn) and attach your material to your object.
b. Select the blend colors node  and in your hypershade work area 
    Middle mouse button drag from the blend colors node to your blinn.
    Select color as the linkage.
c. Select any 2 textures (from files...) or
    Click on the checker and grid textures (they appear in the work area)
    Middle mouse button drag from checker to the blend colors node.
      Select color1 in the popup option box (setting your first texture).
    Middle mouse button drag from grid to the blend colors node.
      Select color2 in the popup option box (setting your second texture).
c. Now "blendColors1.blender" controls switching the objects color display
   from color1 or color2.

d.  You can set the keyframe to switch between 0 or 1 or create a
combination
    between the two textures by controlling the blendColors1.blender value
    by keying the "blendColors1.blender" in the channel box or attribute
editor 
    OR
    You can tie the "blendColors1.blender" to any keyable attribute by:
	1. Double clicking on the color blender node in the Hypershade.
	the attribute editor appears.
	2.in the attribute editor, under Blend Color Attributes.
	right clicking on the word "Blender" and in the popup window selection 
	"create New Expression"
	3. in the Expression editor type:
		"blendColors1.blender = poly1.translateX; " 
		or any other keyable attribute	
		remembering to press the "create" button  at the bottom of the
		expression editor to actual input the expression.
