Job Description

hi my website is optrixstore.com based on magento
i need the prescription options like in http://optrixstore.com/index.php/catalog/product/view/id/162/s/on123bu12/category/13/?feedback=1 to become default for each product.
the effect of being taken to "prescription page" after clicking "add to cart" button in goo.gl/tTWX5 is what i require on my product detail page but for adding/selecting lens options and not for entering prescription.in goo.gl/1Ruso it comes as ajax (not sure of technical name) but i want it to come like in goo.gl/tTWX5 as told before.
for entering prescription it should happen just as in this link goo.gl/aFXtO
i think you will be able to access that link only after adding any product to your bag from this link goo.gl/CejYs

after clicking buy,a question should appear asking how do you want to give presc then various options will come on clicking the respective link as in ditto
The eye power,cylinder,axis,etc options will come when customer selects i will input prescription on my own

i want a new theme for my site which i can provide so install it such that virtual try on & other features of my site remain functional

also an error is coming when i try to export products in magento admin which says:

Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 4976909 bytes) in /home/sshrey/public_html/app/code/core/Mage/ImportExport/Model/Export/Adapter/Abstract.php on line 95

i need this to be solved as well.
