I would definitely check the spark plugs and replace them (some toyotas require dual ground electrode spark plugs, I don't remember if 00' tundra requires). I would also check to see if you may have had a bad batch of gas. When I used to work for Honda as a mechanic some honda's would put out a multiple cylinder misfire. I noticed most people that used ARCO would come in with a misfire code. I wouldn't replace all the coils .. You may want to get a voltmeter and get the specs for checking the coils. You may be replacing some good coils and wasting money. If you don't know how to work on it I would definitely have a dependable/reputable mechanic who is familiar with toyotas.
On a V8 you may not see much of a change doing a cylinder drop test.
I would start with the cheapest stuff first....check Gas...Have you replaced you fuel filter? These codes can pop up due to many different things... Bad injectors,coils,fuel,fuel pressure, etc.. I think its unlikely to be several coils.
keep us updated. I will call my buddy who still works for toyota.
