PROBLEM: My main goal in getting surround sound is to help my husband hear the dialogue! He can't hear clearly when there's any background noise in a movie, it makes the voices harder to distinguish. I'm constantly 'translating' for him & he's only 46! <snip>
No, I don't know what I'm doing.
BUDGET: $1500-$2500 for speaker system, receiver & DVD player. Do I need special wires/cables, powerstrips, etc? $2500 is my max.

Dear Velcrometer.
First, nice nickname!
Second, a better DVD player probably won't appreciably enhance your DVD sound. But that assumes that you have a decent preamp/amp or a decent AVR. Even if your DVD player is les than great, if you send its signal to a decent receiver or pre-amp, you'll be OK. The receiver/pre-amp will then decode the digital signal.
You can find a great AVR for under $300 these days, plus shipping. Do a Froogle search for a Yamaha AV-R659. The newer model, the 661, which'll run about $100 more, but has better HDMI, is great, too. Unless you're building a really high-end system, either of these AVRs will be all you need.
For movie dialog, the center channel is the most important one. It handles virtually all movie dialog, and about 50-60% of all movie sound. Of the remaining percentage, most will be played by the left and right main speakers. Some will be kicked to the surrounds, but beware that many, many movies will have little to no surround sound.
I didn't mention the low frequency effect channel (the LFE), the .1 channel in a system. It's great, and I highly recommend a sub.
When I built my 5.1 system, I was disappointed in how few movies and documentaries sent good effects to the surround speakers. Note that I'm talking about movies and documentaries that had a 5.1 setting in the audio menu; some don't. I though I'd set something up wrong with some DVDs, until experienced people told me that some movies will send little, if anything, to the surround speakers.
Again, let me say that for your needs, a dynamite center channel speaker is paramount.
You can get a fine 5.1 home theater system system for under $800--for example,the AV123 batch of four x-ls's (L, R, LS, and RS) and an x-cs for the center, plus an x-sub. Of course, an AVR would be on top of that, but if you got a Yamaha 659 for $280 plus ~$25 shipping, you'd be well under your budget.
I'm shopping for a new system, and, while I'm considering AV123 speakers, I'm in love with the Phase Tech Premiers series 3.1 II. (Not the plain 3.1's, which are older and not as good, only the 3.1 II's.) These blew me away. They cost $600 each, MSRP, though almost any dealer will give a discount. Three of these (L, R, and C) would make a killer system. You could get much less expensive speakers for the two surrounds.

A sub to go with it? I could recommend some. Hsu, SVS, and AV123 come to mind immediately. Do you want down-firing? Do you have cats with front claws? These are questions to pursue.
AV123 has a dynamite sub coming out, the MFW-15. It's on my short list. There'd be no problem pairing that with a Phase Tech speaker system--or any speaker system.
Special wires? High-cost speaker wires are a snake-oil item. Unless you have speaker wire runs over 50-feet, just get 14-gauge lamp-cord wire at a big home store like Lowe's or Home Depot.
Interconnects? (These are the wires that go between you system components, except from the AVR/amp to the speakers. In other words, interconnects go from a DVD player to the AVR, the VCR to the AVR, the TV to the AVR, the AVR to the TV, the cable box to the AVR, etc.) Please don't fall into the trap of getting expensive ones. The Radio Shack Gold Series are great--they're all you need, and you can find them in every city. Monster Cables? Though decent, they're far too expensive for what they give. You could also find good stuff at Blue Jeans Cable if you can wait for the shipping (great quality):

If you feel you need to upgrade your DVD player, the other references to Oppo are good. Depending on your TV and overall set up, choose wisely, because you may not need all the bells and whistles.
I'd recommend a good-quality surge suppressor. Get one that has a pretty high joule rating. You shouldn't have to spend more than $50 for it, unless you want other features, like battery back-up.
