I just hit 128,000 miles and i'm thinking I might need a major tune up. I was thinking of replacing my cap and rotor but I'm not sure if I have to. What are some symptoms that will tell me that I need to change them?

might as well do it. I just changed mine was easy and not expensive. something like 16 or 17 dollers <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/biggrin.gif" border="0" valign="absmiddle" alt='

When were they last replaced?  As JDM_Siliva said... it's cheap, so why not go ahead and do it.

I haven't looked at mine too much, but how hard is the install? Do you just unhook the battery, pull the distributor wires, pull the old stuff off and then replace?

Well if there is no evidence of them ever being replaced, you may be in luck actually.  You may feel the difference in performance and be one of the statistics where new wires really do make 10hp.  Maybe not, but you're still WAY overdue for the change.

As said above, it's fairly cheap and very easy.  A wire, cap and rotor swap will take 30 minutes, but don't rush it.  
New wires are the most expensive at $50, the cap and rotor are like $7 each at courtesy nissan.

Two things to watch out for are that the rotor goes on two ways, the right way and the wrong way, so just watch and make sure you put it back on facing the same direction it came off and you'll be fine (it would actually be pretty hard to screw up, unless you didn't even look at the direction it was before you took it off).

The other thing to note is that the cap is not in order.  As you go around the order is 1,2,4,3.  Just make sure you don't assume it to be 1,2,3,4 and wire them all in sequence (it's all marked on the cap as well).

what are signs that you need to replace your distributor cap and rotor.  I bought my car used, and I dont know if it has been changed.  I have just about 90000 miles
