It seems to me that you've a ton of programming books, but I think you need more than that. For instance, I guess your work involves networks, databases, possibly user interface design, and so on.
I'd steer clear of books related to particular implementations of technology. Far better to look at books recommending best practises etc. I've thrown out more books than I care to think about relating to particular versions of Java/Perl/HTML etc. However my copies of The Pragmatic Programmer and Code Complete (linked elsewhere in this conversation) remain timeless.
For networks I'd recommend Steven's TCP/IP Illustrated. Having a networking book is invaluable - I find networking to be one of the most comprehensively misunderstood aspects of the environments we work in nowadays.
