Unless your intake manifold is cracked or broken, keep it for now and worry about upgrading it later. Take a wire wheel to it and clean it up if you want.
Get everything working the way it should first, then upgrade.

If I upgrade the carb with a newer one with more barrels, won't I need a new intake manifold that fits the more barrel having carb though? If it is significantly cheaper to stick with a similar carb to the one I have now then I will most likely do that until I can afford a nice one. However, I just want to make sure I have it right in my head, lol.

Awesome, thank you so much. I'm think about ready to make a new thread for specifics on what pieces I should buy. Do you have any recommendations?

Yes, venturi.
Engine cubic inches X max RPM divided by 3456
How do I tell what size carb I need?
Officially (legally) tampering with or removing the factory-installed automobile emissions equipment is a Federal offense under Section 203(a)(3)(A) and (B) of the Clean Air Act.
See Transportation and Air Quality | US EPA
Section 205 of the Act provides for a maximum civil penalty of $2,500 (used to be $10,000) per compromised device for any person who violates Section 203(a)(3)(A) or (B).
See http://www.epa.gov/oms/regs/fuels/cff/memo-1a.txt
There are some states that are no longer mandating tests of "older" vehicles and so some people remove this stuff, but their lack of enforcement does not supersede or replace the federal laws against tampering.
What the vehicle came with out of the factory wrt emissions controls is what Federal law says must always be installed forever. This is something to consider if you the truck needs to be inspected before you can sell it.

BTW Muidem, can you fill out the rest of your profile so we can see where you're at? click User CP in the top-left to do it.
BTW I'm not trying to talk you out of doing the DS2 swap, just explaining what you're getting involved with. What you do is your choice.
If you have a test light or analog voltage meter, you might read the computer codes and see what the computer thinks it's having problems with, here's how:
Ford Fuel Injection
Ford Ranger/Bronco II EEC-IV Testing

To answer an earlier question, you could use a stock manifold with a 4 bbl carb, but they aren't designed to flow very well and would pretty much cancel out any benefit the 4 bbl would provide. Now a 2 bbl on the 1 bbl intake, I could see that- but not anything bigger.

Thanks so much for all yall's responses so far. I've learned a lot from this thread alone. I went to the junk yard today hunting for some pieces and I've made a thread about that. When I have more specific questions, I'll go ahead and open a new thread. Thanks again =)

I just wanted to say good luck with your new truck! 300 - I6 is an awesome work truck engine.
Just give her a full tune up and have a compression test done. This will get you off to a good start to begin with. You'll know she's tuned up and know what condtion the engine is in.

another way is with a D.U.I dizzy. setup
one wire setup like and IMHO it's worth it, you can toss the engine wire harness as well as the 
ECM if smog test are not a state issue
real simply hook up and for 400 bucks it's worth it
