Detail Steps:-

Once you read my article http://sharepoint.infoyen.com/2012/04/11/create-and-deploy-user-control-in-sharepoint-using-feature/ then you will understand that how to create, deploy user control using feature.
To pass webpart property into webpart follow below steps:-

1. Create web part property for example “EmpoyeeName” in webpart class “GenericUserControlPicker” , as mentioned below:-

private string employeeName = string.Empty;
 
[WebBrowsable(), Personalizable(),
WebDisplayName("Employee Name"),
WebDescription("Employee Name")]
public string EmployeeName
{
 get
 {
  return employeeName;
 }
 set
 {
  employeeName = value;
 }
}

2. Create regular c# .net property in user control as “EmpoyeeName” in user control class “HelloWorld”, as mentioned below:-

public string EmployeeName {get;set;}

3. Pass webpart property “EmployeName” value to user control as mentioned below code:

// this is line number 51 in "GenericUserControlPicker" class
userControl = (UserControl)LoadControl(UserControlPath);
// Check usercontrol is loaded or not.
// Also check if Employee Name has been entered or not
if(userControl!= null && !String.IsNullEmpty(EmployeeName))
{
 userControl.EmployeeName = EmployeeName;
}

4. Display webpart property “EmployeName” in user control, as mentioned below code:

protected void Page_Load(object sender, EventArgs e)
{
 lblTest.Text = EmployeeName;
}

Hope It Helps...
