Whenever I put my gearing to the big boy, it rubs up against the front part. i think it is the front derailleur its called. I loosened the top screw on it a lot but still it rubs against it and I don't want the screw to fall out

If I hold the shifting (shifting from middle to big ring) all the way to the right as far as it goes, it won't make that rubbing/krrrrring sound. So for a good portion of my rides I have been holding the shifter all the way to the right so I can ride in my 52. if you pass me it looks like I am changing gears but I hold it there

I ride a 52/42/30 front and a 12-26 on the back. Shimano 2300 shifters/ front derailleur / rear derailleur

You need to tighten the front shift cable tension.

You've been adjusting the wrong thing. Use the instructions found at parktool.com. Do each of the steps in proper sequence leaving nothing out.

^ What @HillRider said.

Drop your front shifter to the smallest chainring (lowest cable tension). Then, loosen the cable clamp nut at the front derailleur, and tighten the cable a little bit. It shouldn't take a whole lot. Tighten the clamp bolt again, and see how the shifting works. If you've got a barrel adjuster for the front, use that instead. Turn it counterclockwise to increase cable tension. Depending on how much you tighten the cable, you may need to tighten screw that hi limit adjuster screw you loosened a bit.You'll know you have to if you try to shift to the big ring and you drop the chain

What you're adjusting is the limit screw; there are screws for both the front and rear derailleur. Those are best left to a shop unless you really know what you're doing and you'll find you won't need to touch them much, if at all. The adjustment you can do yourself are the barrel adjusters -- there are ones for both front and rear.

Generally, I've found I almost never need to touch my front, but then I don't go from top to bottom much when riding. Try turning the front barrel adjuster counter clockwise, but start out at no more than a quarter turn increments and stop when you've got better shifting.

Ok is this what I shoud read and follow Park Tool Co. » ParkTool Blog » Front Derailleur Adjustments

That worked. I loosened the barrel adjuster on the chainring shifter side. The side that changed from big to small chainring (left hand. I apologize with my ignorance on part names.

But now When I shift to the big ring from the middle, the front derailleur "stops" the chain and it gets caught. That will be a problem and a great way to fall when i ride. what adjustment is that? limiter since i was messing with that?

Yes

Yes, it sounds like the low limit screw isn't adjusted correctly.

But as other people said, start from the beginning. Adjust both the low and high limits, and then get the cable tension set. Otherwise you can end up endlessly chasing adjustments around and never getting it right.

Google adjust front derailleur and study the parktool.com and sheldonbrown.com tutorials first. As noted go through the entire process, including checking the derailleur rotation and height. If you still have trouble try actually talking to someone in-person, such as at a bike co-op or a bike shop or even a knowledgeable friend. That's what folks did before the Internet.
