Portfolio & home page on Iphone

Hi there,
I would appreciate if you could help me with the following issues:
1. on the home page – photos in the slider look quite small on the Iphone (the size is fine on the Ipad and laptop)
2. on the portfolio page: photos are very slow loading on Iphone and Ipad
3. on the portfolio page on the Iphone when the product is showing the buy button and the price are at the bottom of the page while on the Ipad and laptop are at the top near the photo. Could you move those two for the Iphone to be the same as on laptop and Ipad?
4. How could I remove the date on the portfolio page under the photo of each product near the details tab?
5. How could I remove on the portfolio page the following: “Leave a reply, your email is safe with us”?

As always I am very grateful for your help. You guys are saving hair on my head!!
Have a nice day and thank you,
Irena
