1. I have researched that a 120.4 can do a cpu and a gpu plus maybe something else but since I cooling 3 gpu and cpu and maybe even the ram being liquid cooled leads me to ask: Should I get 2 thermochill 120.4? Which leads to next question
A 4x120 rad would barely be enough to cool a CPU and 1 GPU. Rule of thumb: a single 2x120 worth of radiator per CPU or GPU or larger rads that equal this (which is commonly how it is done.)
You are looking at the ballpark equivalent of two 3x120's and one 2x120...or two 4x120's.

2. If I need two rads in the loop would I need a second pump to ensure good flow?
No, but in a 3X SLI + CPU loop, you might consider dual loops or a big pump like the MCP655 or MCP35x. Dual loops could run a smaller pump like the MCP355's, but even those are very powerful, especially with an aftermarket top.

3. Depending on the number of pumps and rads the loop would look like ( feel free to tell me a good loop as I never liquid cooled more than a cpu )
one pump: ( 1rad - RES>PUMP>RAD>CPU>RAM>GPU's ) or ( 2rad - RES>PUMP>RAD>CPU>RAM>RAD>GPU's )
two pump: ( 1rad .- RES>PUMP>RAD>CPU>RAM>GPU's ) or ( 2rad - RES>PUMP>CPU>RAM>PUMP>RAD>GPU's )
Loop order doesn't matter as long as the reservoir (if you have one) is above and feeds into the pump...the rest of the loop order doesn't matter...your temps will only be a few degrees Celsius different at any point in the loop, provided you have adequate flow and enough radiators to dissipate heat.
Don't WC your RAM...its a waste of money and won't benefit your overclocking at all. (See comments/suggestions below on RAM cooling...response to #7)

4. Would you buy the thermochill TA 120.x over the thermochill PA 120.x? quoted from their website "The TA series features the same great build quality you have come to expect from the PA series, but with an improved core, G1/4" ports and 15mm spacing to ensure full compatibility."
It's in your best interest for you to learn what is good for your setup and budget.
I think this is what you are looking for:

5. Now the case comes into question the silvertone tj07 seems to have good amount of room for a couple 120.3's. But I was looking at
http://www.mountainmods.com/CYO_picker.php and might get an extended u2ufo case made to ensure enough room for two rads pumps and res and everything else in the pc
MountainMods cases are awesome...and have a ton of space for big water loops, depending on the case and application. You are going to need more than 2 triple radiators for your loop, regardless if its a single or dual loop setup.

6. Anyone know of any front panel drive bay type of flow displays that have an auto shutdown function incase im not at home and my flow stops it can shut off my pc befor things get too hot?
I've had the same MCP655 for 5+ years and its still running...in fact, I'm using the PC now.
If you are concerned about temps+shutdown, most thermal monitoring software like RealTemp and CoreTemp have the ability to shut down the PC if your CPU reaches a certain threshold. Consider that (free) before buying anything. Plus, most motherboards have the ability to shutdown due to thermal issues.
(You sound like you don't have much trust in water pumps...maybe you are considering the wrong hobby.......?)

7. Haven't decided totally on the liquid cooling of the RAM but I think I want to just for the heck of saying I have it cooled too what would you suggest to cool it the thermal take
http://www.thermaltakeusa.com/Prod [...] 46&ID=1622 or koolance
http://www.frozencpu.com/products/ [...] zzles.html ( I like the look of this koolance one ) or some other liquid ram cooler?
Don't watercool RAM or MOSFETs. The blocks are incredibly restrictive and you don't gain anything from it. DDR2 and DDR3 run very cool as-is. If you want a cooler, consider a fan cooler like these:

8. While looking at the u2ufo case modding I see I can that I can have the MB horizontal instead of vertical would this have much affect to the flow through the GPU liquid parallel block and the CPU? I wouldn't think it would make much a different since its about liquid pressure and not much gravity ( I know about max height for the pumps loop ) for the fluid dynamics of the loop
No, doesn't matter. Once you have a filled loop, the gravity has no bearing on water since it is in a constant state of push/pull by the pump. Consider a train that goes in a circle; and the engine loops around to couple to the caboose, forming a single, complete train...it is both pushing and pulling at the same time, uniformly.
