Answer 1

I can provide you some Logic which may help you to accomplish this requirement.
Create one Visual web part with the user control which has html as per your requirement,
To get the data from the datasheet use the Code to read the data from Data sheet
When you want to display the data for the First week create one varible and maintain it to identify the sequence of week to get from datasheet.
First time When you access the datasheet set this varibale with your week of year number.
Condition the reading of datasheet with this variable like IF variable is null then assign it the week no of year.,
Check this variable next time you come to this logic that If variable is less than the week no current week no of year then take datasheet last you get + 1 means Datasheet 2 and so on
..
Sorry for bad english
variable : one for DaasheetNo, WeekNo,CurrentWeekNo
assign datasheetNo = Sheet1
If(WeekNo== Null)
{
first time getdata from DaasheetNo (First Sheet)
}
else if(WeekNo < CurrentWeekNo)
{
Get data from datasheetNo +1
}
Hope it helps you

Answer 2

This is called weekly update Webpart in SharePoint.
My Idea:
you can set one CurrentDate value like DateTime.Today to Current Web properties.also set one more properties which WorkWeek users. now check
SPWeb web = SPContext.Current.Web;
if (string.isnullorEmpty(web.Properties["CurrentDate"]))
{
web.Properties["CurrentDate"] = DateTime.Today.Tostring();
// do the stuff for displying data.
}
else
{
if(IFChangeNeeded())
{
// do the stuff for displying data.
}
else
{
web.Properties["CurrentDate"] = DateTime.Today.Tostring();
// do the stuff for displying data.
}
}
IfChangeNeeded() is function which return bool value. this function check that employee need to change on this week.
public bool IFChangeNeeded()
{
DateTime PropDate = Convert.ToDateTime(web.Properties["CurrentDate"]);
DateTime TDate = DateTime.Today;
if(WeekNo(TDate) == WeekNo(PropDate)) // WeekNo is function return weekno from current date.
{
return true;
}
else
{
return false;
}
}
