Upgrading - need advice

If you're just switching your motherboard (that seems like a waste of money), then you should be fine.

Its a motherboard, RAM and CPU bunde. So slightly more than "just" a motherboard mate.

I think you current PSU will be fine, gien that your choosing to keep the GPU as before.
 
All in all that looks like a pretty good deal, should make for a very solid foundation.
