[Q] Modified Android Market APP

Hi.
I'm searching for Android Market application which is modify to:
- only download application to folder on SD (not installing)
- doesen't see my installed application on my phone,
- doesen't to be able to install application from computer (Google play site)
- doesen't updating itself

I want to be sure of this, that nobody install application without my agreement on my device. (like a "Services Google Play")
I was trying to modify this application myself but i am to poor in this.
Actually I haven't any google apps on my droid
My device:
(Xperia Ray GB 2.3.4 4.0.2.A.62 Rooted, Bootloader unlocked, DooMLoRD's kernel, CWM Recovery)

Sorry for my English, I'm from Poland, but I am trying to write correctly and understandable. :)

Does anyone find that modification?
Or someone have solution to solve those problems?
