Arduino Web Control

I have written a rough working framework for a zone controllable thermostat for myself. Much of the scheduling and temperatures are hard coded (temperature can be raised /lowered by a buttonread. I have a 20x4 lcd to display current state physically. The arduino serves a display only web page that updates the temperautre sensed, whether or not the zone is being heated, and the current schedule. I would like however to the have the following done: 1) Set up the page so that it is more suited toward iphone / ipad / android tablet viewing 2) Create a secondary page to make it possible to intake data into the variables (schedule times, temperatures, etc). ( a scroll temperature choice would be nice). 3) Create a password protection capability so I can access this device remotely. 4) Have the ardiuno save a daily file of temperature reading that can be remotely downloaded from the sd card.
