Message Considering you will want to take your time with it.

I've done it multiple times on multiple cars, and I would definitely recommend replacing all six. I replaced a single injector just to have another fail 1,000 miles later. Ended up replacing all six (including the one I had replaced already)

Also, don't get injectors off ebay, I've done that too, and guess what I was replacing during the next oil change... Luckily they were under warranty (RETURN warranty, not going to put more venom injectors in there) but having to tear it apart sucks. Live and learn, everybody is on a budget at some point.

Things I would personally recommend doing while you're in there:

-Replace all hoses with Z1 silicone hoses (they only cost a little bit more and will outlast your car). That is: PCV, IACV hoses.
-Stock up on silicon hoses (eBay) for all your 3mm, 6mm, 8mm hoses because every hose you go to pull off will break. I recently bought 40 feet of different sizes for $50 on eBay.
-Upgrade to pintle-less injectors (if its an NA I'm selling a complete setup I bought from Bernie, minus connectors)
-Delete the TB coolant hoses
-Delete the rear, drivers side exhaust VC PCV hoses (there are already baffled PCV hoses on the intake covers for both sides which don't suck up oil)

If you haven't already, you will need to spend some time cleaning corrosion out of nearly all the electrical connections, and you will probably need to replace a few of them that break while you're taking them apart.

Have fun with it!
