I don't personally know what difference it will make if it's an automatic or a manual transmission as EVERY motor I've ever removed at this point has been an automatic.
I CAN tell you that it IS fairly easy to remove the 4 cyl from the top. All you have to do, is disconnect all the wires, disconnect the intake and exhaust manifold, disconnect the A/C compressor and hang it off to the side, and then disconnect the waterpump hoses too. You will need to remove the starter (hang it off to the side) and unscrew the bolts off the flywheel from within the starter hole location. You will have to rotate the motor (not with the starter) until you've removed all the bolts from the flywheel. Then, hook up the engine hoise, and unscrew the bolts from the motor mount first, and then undo the bolts from the transmission to engine casing, and you should be able to pull it out.
You'll need to remove the decklid temporarily.
I HAVE actually been able to remove a complete V6 through the top... with Cyl heads still attached.
Unless I'm going to be fiddling with the transmission, I find it MUCH easier to pull the motor from the top and not worry about the cradle.
In a perfect world, if you had all the space, and a large (free) garage that you could easily move your Fiero around in, the cradle dropping might be easier.
But, I have an 81 TransAm, sitting right next to a 73 VW Transporter in my garage. When I remove the motor from the Fiero, I do it in the driveway.
