+1 for t-lok and gears if you're looking to get the most gain for your money. Yes, its more money but you'll feel every dollar in performance gain. You'll need a sensitive butt to feel any gain the headers will get you.
Or, put the money toward a paint job and get rid of that horrible color

Ok for gears you're gonna want FRPP(Ford Racing) brand. 3:73 or 4:10 ratio.
For the LSD, most people get the Ford Trac-loc but you could also get a Detroit Tru-trac with the necessary bearing kit.
There isn't an actual HP gain, the gears just improve acceleration and make it feel like a lot more power.

A traction Lok rear causes power to be distributed evenly to both drive wheels.
The lower the gear (higher numerically) provides more mechanical leverage (torque) to the engine output. In your trans 1st gear is your low gear and the overdrive is your high gear.
In your rear you only have a single gear so moving to a lower gear, such as a 3.73 or 4.11's gives you quicker acceleration off the line. the trade off is the engine will loose top end speed since it will reach its max engine rpm sooner than if a higher gear is installed. Thanks to modern overdrive transmissions you can swap to a lower gear ad still have good gas mileage as you aren't twisting the engine all that much higher on the highway.

not absolutely necessary but it doesn't make much sense to do at a later time. for 1 your going to have a much harder time getting traction with the lower gear and an open rear - all the power goes to a single drive wheel. and 2 the labor is already being done when the gears go in so you'll pay for the labor a second time if you wait.

The Eaton can handle more power than the T-Lok but FRPP part is plenty strong unless you plan to go with a major power adder and run slicks. In that case a 8.8 take off which comes with a t-Lock and can handle more power would be the better starting point for most people.

As a rule of thumb for a typical street car 3.73 with a stick and 4.11 for an auto. There are pro's/cons in each case depending on your performance goals, future mods and street/highway driving miles. Use forum search tool on gears for plenty of past discussions on this topic.
