Interested in less expensive way to perhaps diagnose and fix "hesitation" while driving at certain speeds?

Coming from picking my son up at camp. On way home noticed a "shuddering" as I was driving. My car is 13 years old with alot of miles. On limited income so new car is not option. Bought in to get check engine light read. The following codes were given:

P0138
P1336
P0300
P0325

Not sure what all means, when I began to call around most mechanics want 100 dollars to diagnose on top of repair. I am looking for less expensive options if any at first. Because of the misfire I thought to start with new plugs. I did have a complete tune up 1 1/2 years ago. Could and should that be the starting point to at least address the hesitation?

I looked at this question earlier, and someone said to me, that a car can't run without the crankshaft sensor. Is that true? I have this same screwy problem, where it misses now and then, and shudders on occasion too.
