That seems to include one of the more expensive flight bags in their range. It depends how flash you want to be.
I had all my stuff for free when i put a large deposit down for my PPL, but was told it was worth around £200, as it included all the textbooks, a CRP-1, and a nice basic flight bag.
If you want to buy you own headset as well, the price is going to be going up and up. If I were you I would source things individually. As has been said, the Jep will be provided when you sign on for your ATPL, and you wont really need the CRP-5 CD-ROM, as you will be taught at length how to use the CRP-5. Its not very hard to use, just tricky to be totally accurate.
The map will go out of date all the time, so you may want to sign up to a subscription service to keep up to date.
