Tune up = AC Delco electrical only. These blazers do not like other components. Get the plugs, rotor, cap, wires all AC Delco. That's what has been said in here for a long time.
MAF - Mass Air Flow sensor. Search in here & clean it, it's easy to do & cheap. That should be a must depending on driving conditions - dusty, aftermarket air filter IE oiled too much (common thing that happens).
A 2000 blazer has a EGR Valve, that should be looked into as well & a search in here will tell you how to clean it.
Try those things & let us know what the difference is... preferably in steps like the plugs, then the rotor & cap, then the MAF then the EGR. Doing things in steps like that gets you familiar with the ongoings of your vehicle. What does what & how it/they effect things.
You said it needs a tune up so that's where I'd start & what I'd do... in steps.
Get to an AutoZone or some place that will scan the vehicle for codes as well. Just because the Check Engine light isn't on does not mean there aren't any codes.

You're tune up will consist of: Spark plugs, Distributor cap, Distributor rotor, and spark plug wires including coil wire. All parts accept the plug wires MUST be AC Delco, The plug wires can be Autolite, they are better than AC Delco and also cheaper. I believe all parts can be found on Amazon for a good price, either that or Rock Auto
The tune up is relatively easy to do yourself. For information on how to do it, do some quick searching on here.
AHH DAMN!!! you got it while i was typing... well dual info never hurts

Tuning it up may take care of that.. Cleaning those things & replacing the others may get rid of the shaking. Try the tune up & get the codes checked 1st.
