As far as re-sizing goes, look up in the upper left hand corner of the POV-ray window, right under the "open" icon.
See the little box which reads [512x384, no AA] with the little "down" button next to it.
Click the down button and you will bring up a drop menu with different rendering sizes you can use. Click the one you want. ( Note you can choose between "no AA" and "AA 0.3". This selects the amount of antialiasing the scene renders with. Antialiasing renders slower but gives a smoother looking render.
As far as textures go, in the screenshot I see four textures declared (t0,t1,t2, and t3)
You can alter the textures by changing these declarations.
The lines that read

#declare t0 = texture{
pigment {color rgb <0.1,0.4,0.9,>} finish{ specular 0.5 roughness 0.01 ambient 0.35 diffuse 0.32}
|
set the parameters for one of the textures, both the color (red 0.1, green 0.4, blue 0.9) and the finish ( how much and type of high-lighting you get, how much ambient lighting and diffuse light comtribute.)
You can also add "normal" which will determine the "bumpiness" of the texture.
