Mouse Map

I'm looking for a way to make a map of my total screen area (800x600 etc..) so that I can measure the position of my mouse pointer with a numerical value.

I then want to combine keyboard and mouse commands so that they perform whatever action such as a mouse click at whatever numeric position I set. It should also be able to handle any amout of commands for an unlimited amount of time.

I'm wanting to teach my computer to do things like check and download my email automatically while I'm away from the computer so I can look through it later without having to login.

Example:

I have a freemail email address on yahoo.
I want my computer to automatically log onto the net (open browser) at a certain time.
The browser will have a set window size that will measure up with the numerical value of certain links that never "seem" to change on that web page.
After a set amount of time (maybe 5-7 minutes - estimated time for page to load), when the load time ends, the mouse will have been moved to a numeric postion where it will click on the link for "Email".
Sometimes it will need to login to the account, so it can either have it's own user/pass library or it can use the save user/pass in IE.

I'm very new to programming and right now I'm mainly wondering what the best language to use would be.

Any ideas would be useful.
