I personally have no expertise for DWC, so Ill leave out the soil/pots. If you decide to go soil/soiless these items are quite a bit cheaper from the store anyhow, I can tell you what I would use. If you are planning to go with any more than 2 1000w lights then I would look into 220v wiring, and a controller. I can discuss those options with you as well. For up to 2 lights, separate timers on separate circuits will do. If you are going to go perpetual, I would invest in some T5, or 200 true watt CFL. Or just another MH setup. I can recommend some options in that area as well.
I would just start with the items you need for seed starting/clones, and build up as you go. Once you get clones/seedlings started under your first light that will buy you a few weeks.

Nutrients cheaper (never used these, but on a budget, these will probably be ok to start. Or you can probably shop around for something cheap. ) $17 shipping included
http://www.amazon.com/Pure-Blend-Pr...?s=home-garden&ie=UTF8&qid=1327614305&sr=1-46
Nutrients Ideal $27 shipping included GH flora, I use it, they work, and they are popular.
In a 5000w grow, like $300-400 of General Hydro nutes last a full harvest, so definitely worth the money as I know they work. If I was trying to save money in this department, I would go General Hydro FloraNova 2 part, or Dry 2 part. I personally also use the GH brand supplements as well , but you can either skip them or use another brand. They are very overpriced in any big name brand.

MISC ITEMS:
Reverse Osmosis: I use this model and it works great. Ive priced out different brands and the cheaper alternatives are priced close and are probably lesser quality. I have only heard good things about this guy. If you do use RO water, be sure to get a calcium/magnesium supplement. I use GH Cal/Mg and love it, also lowers PH so I never need PH down anymore.

PH Tester: Using water at the right PH makes a huge difference, especially if you are going with the DWC.
http://www.amazon.com/Milwaukee-Ins...1?s=home-garden&ie=UTF8&qid=1327614879&sr=1-1
PPM Tester: I use RO water, so I barely use this, I just follow recommended dosages from the manufacturer for nutes. But I do own one as should you eventually. In DWC it is probably necessity. I use a cheap one like this, though quite rarely, but it works fine.
http://www.amazon.com/HM-Digital-TD...1?s=home-garden&ie=UTF8&qid=1327615084&sr=1-1
Ducting: Basic ducting. I started using insulated ducting from Home Depot similar price, but it isnt that great to work with. Now I use hydrofarm brand lightproof silver duct. I use it in 8, but you can use whatever depending on your needs. I would just match your equipment flange size to save on needing the reducers and connectors.

Pruning Snips: These are my go to for pruning and trimming. Good quality, comfortable, and easy to work with. When Im lazy I cut my clones with it too. If you want to splurge they also come in titanium.

Stand fan: Gonna need room air circulation. I use 3 of this exact brand. They are cheap plastic materials, but work well for the money.
http://www.amazon.com/Lasko-16-Osci...ONUS/ref=sr_1_1?ie=UTF8&qid=1327615581&sr=8-1
Light hangers: I use tie down straps as light hangers. For the money/ease of use/quality/durability Ive not found anything cheaper. From Home Depot it costs me $5/light with 2 straps each, these are similar. Dont want to skimp on these with so much money hanging from them, but I trust these. Dont know this particular brand, but the reviews seem good.

Clone Dome: I have been cloning in aero as of late, but I used to use something like this, and will likely go back eventually.
http://www.amazon.com/Planters-Prid...9?s=home-garden&ie=UTF8&qid=1327616693&sr=1-9
Carbon Filter: For Odor control, Carbon filtering is my #1 choice. I have recently been using PhatFilter brand as I feel it is good value for the money, but this brand seems well reviewed.
