1. I have a base model w/o LSD (2004 actually), do I still have to change the diff. fluid? If so, do I still use the same type of fluid that you guys uses for LSD, or look for a different one? I'm currently leaning towards the Redline brand, so what should I use within the Redline line?
2. Being that I've never worked on my car before, where should I look for the Tranny and Differential? All I need is the general area where they're located after seeing the detail pictures that OP took. Thanks.

If you have never worked on a car, just make sure that the car is well supported by stands. Don't rely on a jack while you are under the car...

Yes four stands would be the way to go. That's how I do it as I have 4 already. They are cheap to buy.
You want the car level to fill up properly. I do believe that a little more or a little less because the car is not level is not going to hurt anything...

Well I found a local distributor in Houston. They carry all the Redline products in store.
ProAm
Richmond Ave.
Houston, TX 77057
(713) 781-7755
After alot of research, this is what I decided to go with:
Differential - 2 qts. 75w90 Synthetic Gear Oil (GL-5)
Manual Transmission -
2 qts. MTL 70w80 (GL-4)
2 qts. MT-90 75w90 (GL-4)
The 2 different weights of Manual Transmission Fluid are combined to create a weight closest to that of what Nissan calls for. Reason being, is because Redline does not offer an exact 75W-85 weight. I found this information on another website. I decided to cite the info here, to clear up any misconceptions as to why 2 different manual transmission fluids are used.
Product information can be found here:

Nissan calls for 75W-85 oil. Many owners suggest using Redline fluid, but the do not offer the exact oil weight so this requires a mix if using Redline fluid (2 quarts each):
Redline MTL: 70W-80
Redline MT-90: 75W-90
Redline MTL: 70W-80
Redline MT-90: 75W-90

75W90
Our most popular gear oil, this is the preferred product in nearly all car and light truck differentials, both conventional and limited-slip. 75W90 is preferred for most racing applications. It contains friction modifier which is recommended for limited-slip units. 75W90 Gear Oil can be used in many transmissions and transaxles; however, other Red Line lubricants have better frictional properties for rapid synchronization. Exceeds API GL-5.

75W90 NS
This GL-5-type geal oil doesn't contain the friction modifiers for limited-slip hypoid differentials. This makes the transmission synchronizers come to equal speeds more quickly, allowing faster shifting and much easier low-temperature shifting. Can also be used in racing limited-slip differentials where weak spring design causes too much wheel spin.

Transmission & Differential Fluid Change. Lots of Fun Under the Car. Pics Included.
My 2003 Touring finally hit 30k. For the past week, I've leisurely been changing out the tranny and differential fluid. 1st step was to get the car lifted to a good working height. Nothing like a good set of jack stands to get this done. I have light duty stands that are almost flat on top, to keep from denting any of the undercarriage.
More pics to come in a few minutes..

Next came a good choic of fluids. I went with Redline products. They sell them locally, so I was able to swing by after work and pick some up. Pretty pricey stuff!

Wouldn't you know it. I still needed another tool. All the tools I already have, I was missing a 10mm hex socket. A local stop at Sears rectified this. The entire set was on sale too.

Ah, nothing like working under the car.... If anyone hasn't ever smelt used differential fluid, trust me, you'd wear a mask too. The smell still hasn't gone away. It smells like a combination of a stink bomb and tar.
You can see all the crude and metal shavings that build up around the magnetic portion of the drain plug.. Good stuff.
