Answer 1

Try to put this in your head from your webpage:
<meta name="apple-mobile-web-app-capable" content="yes" />
<meta content="minimum-scale=1.0, width=device-width, maximum-scale=1.0, user-scalable=no" name="viewport" />

Answer 2

Okay... that's completely clear, why you've got a fixed height... in your body you set height to 748px... thats not variable.
Try something like this:
I used this in my webapp and it worked fine:
body {
position: relative;
margin: 0;
-webkit-text-size-adjust: none;
min-height: 416px;
-webkit-touch-callout: none;
}
I tried to edit your code, but i don't know, if it will work for you. please have a try:
body {
width:2048px;
min-height:748px;
background-color: #fff;
overflow: hidden;
font-family:Verdana, Geneva, sans-serif;
-webkit-text-size-adjust: none;
-webkit-touch-callout: none;
margin: 0;
position: relative;
}
