What must I absolutely upgrade?

Here is my set-up:

Sony STR-DE685 Receiver-

And I use a PS3 as my Blue-ray player.

I also have poopy, old pioneer HTiB speakers from my college days (90's, lol). But I do have a pretty sweet and pwerful Sony Subwoofer.

I know all of it is outdated, but I would really like to get by with minimal expense. The wife and I want good movies and good music, but our "Home Theatre" system is just in our living room. I am a teacher so money IS an issue, lol. Basically I just want to know if I can get by with everything except maybe the speakers. Or in other words, if could only spend a little dough, what would you do??

Is a HTiB out of the question for me, even though I don't have a legit "Home Theatre" set up?
