Welcome to the forum! I will start by saying that no question is a dumb question. We understand where you are starting as all of us have been/are at the same point. Don’t be afraid to ask, as you will not learn if you do not seek the knowledge.
Now then, some folks have taken these engines upwards of 500hp in stock form but it is not typically recommended. Your engine should handle a turbo no problem, given that it is in good health (rings, bearings, oil pump, etc). You are not going to want to crank the boost way high straight out of the gate though. Low boost and work through it one step at a time. If you want to go turbo, that’s where I would start. Keep the engine stock and turbo it, then work up to your heads and cam later. If you pick a cam right now, it won’t match your heads and intake later. If you get the cam you need for heads you’ve got picked out for later, then it won’t match what you have now.
You follow me?
If it were me, I would completely go through the suspension and brakes. Find the tubular k-member and control arms you want for the front (you need it for the clearance with the turbo). Get a good set of subframe connectors. Decide how you want the rear end set up (irs or torque arm/panhard bar). Then work toward regearing because the turbo is not going to play nice with those 4.10 gears.
