hi there to change user account name click on the start menu then control panel double click administritive tools then computer management
click on local users and groups then click on users
you should now be able to see the account you want to change its usually at the bottom just right click on it then rename.
WARNING dont try to change the built in administrator account usually at the top of the list as you could lose access to programs and any work/documents/ settings etc .
exit computer management that bit done when you open the start menu now your desired name should be there at the top.
right click on my computer then click on properties then click on computer name there you can change the name of the computer to whatever you wish
as for ie i dont think it stores personal accounts just go to control panel internet options on the general tab click delete under browsing history when the next window appears click delete all. im presuming your using ie7 .
as for your internet connection do you have router or modem ? if you have a router you should be able to plug and play using your ethernet cable if you have modem you will have to install the software for it and input your username and password in the dialog boxes
hope this helps dan
