You need to define *what* is slow -- is it internet access, file-sharing between computers in your network. What is slow?
We have
Sony Vaio = 802.11 b/g
Dell = 802.11n
Acer = 802.11 a/b/g / draft-N
We have 2 X Box 360's
How do the Xboxes connect to the Netgear -- wired or wireless?
We also have Western Digital 4 Terrabyte shared hard drive plugged into the router
Presumably as a NAS device.
Can we upgrade to Netgear DGNB2100 N300
Yes but if it is internet access that is slow then putting it in will not solve your problem.
Plus a ( WN111 USB Adapter ) for my OLD Vaio with 802.11 b/g
Try to understand the numbers. Assume you are reasonably close to the exchange and you have an 8MB/Sec broadband connection. The netgear will apportion chunks of that proportionately to each connected device.
So now look at the connected devices. The 802.11G devices are 54 Mb/sec and in real world will do 10Mb/sec but this still exceeds the speed of the broadband connection going through the DG834G. Putting a 802.11N device may give you a faster wifi connection to the router but internet access will be no quicker.
Where you may notice a difference in speed is in file/print sharing within the local network -- like to/from the WD 4Tb.
If you've got too many devices all sharing the broadband pipe then adding the N router won't make that any quicker. Where N can be a real benefit is in the range(distance) of the wireless penetration.
Will the X Box 360's still work?
Assuming the XBoxen are G wireless then as long as the wireless setting on the DGN is set to multimode then yes -- it will negotiate the best speed for the connecting device.
