I need a rundown on what I need for a complete charging station, Links appreciated. I am new to electric and lost in the sauce.

I'm guessing you are charging batteries for the E-Revo. High capacity 3s,4s,5,6s packs?
Here's a good power supply:
There prices are a little high, you can probably find them cheaper elsewhere. Or give them a call, I know they like to take % off their merchandise. They do have good customer service!
As for the powersupply, if you're going use the chargers listed above 30amp power supply is the minimum I would use. You have to have the capacity to push through the charger to charge these high capacity batteries. These chargers, the 720i for sure, will also give the expandability of charging at higher "C" rate with specific high "C" charge rate packs.
Just a quick pointer also, theres a tab at the top for searching the forum. Its real helpful and I'm sure you could find your answer in a couple clicks.

Charger: I use an MRC Super Brain 989, which is an amazing charger, capable of charging 1-8 Li-Po/Li-Ion/Li-Fe cells, 1-25 Ni-MH/Ni-CD, 6-24v Lead-Acid/Gel-Cell/PB (1:1 car & motorcycle batteries)...up to 19900mAh (nineteen thousand nine hundred). It will charge (up to 10A), Discharge (up to 10A), Cycle/Revive (up to 9 cycles), comes with a temperature probe that you attach to your battery, and if the temp of the battery reaches the value you set, it will pause charging until the battery cools off and then resume charging, has 24 battery profiles you can save so you never have to reset it for each different battery, has more adjustments than you could imagine, has a 1-30v 10A output for running tire truers, com lathes, soldering irons, & any other DC device that you need to have 1-30 volts and 0.1-10 amps to operate, it has a motor break-in feature for correctly breaking in electric motors (can use temp probe), it has this awesome thing called MRC SafeGuard Technology which checks the battery specs/stats and will warn you if you have set it up wrong and/or automatically change your settings to bring them back to a safe level for that particular battery...like if you try to charge a 500mAh pack at 10A, it will warn you, and/or automatically reset the charge rate to 0.5A like it should be (it can be over-ridden, though), and it has special proprietary peaking & peak detection technology (and has a re-peak & top-off mode), as well as a few other special things MRC developed (and patented) to make sure your battery is charged, peaked, discharged, cycled perfectly and more accurate than any other charger on the market (so they say). It costs $165, but it comes with a VERY nice power-supply.
*** Bold Blue - I believe this is the only charger with this feature. ***
Power-Supply: If the charger you buy is DC only and doesn't come with a power-supply, you will need to buy one as well.
Balancer: If the charger you buy doesn't have a built-in balancer, you will need to buy a good one, preferably one that will allow you to charge/balance multiple packs at the same time.
Safety: If you decide to go with LiPo batteries, you will need to buy a LiPo sack. LiPo sacks are small bags that you put your LiPo in when you charge it...it is fire-proof and explosion resistent in case you try to charge a bad LiPo or try to charge your LiPo incorrectly.
Batteries: This is simple, I suggest you go ahead and run LiPos, and the LiPos I recommend are the 30C ***** ********* LiPos from *********.com. You can run the 25C Zippies as long as your total mAh is at least 5000mAh.
Connectors & Adapters: You will need to buy and solder on the connectors of your choice to all of your devices, such as your charger, batteries, speed control, motor, balancer, etc....and I personally recommend Deans Ultra plugs, but the Traxxas High-Current plugs are great as well.
You can charge multiple batteries at the same time on any charger, you just have to wire them i series and make sure the total number of cells isn't more than the total number of cells the charger can charge...
...like, if your charger can charge up to 8 cells, you could charge two 4S packs at the same time, or four 2S packs at the same time, or a 3S and a 5S, or any number of packs as long as the total number of cells is less than or equal to 8 (or your charger's max)...the only thing you have to do is make sure all of the packs you are charging at the same time are the same brand and capacity, or it will cause problems.
You will also need to buy or make small main-lead adapters to hook up your batteries (in series), and if you don't have a balancer capable of charging multiple packs built-in, you will need to buy or make a balance-plug adapter to make the balancer see the multiple packs as a single pack.
If there are any typos, spelling or grammar errors please forgive me, as I am very tired and do not feel like correcting anything right now.
