Front derailleur never alligned
Well, for one thing I would suggest trying to fix this problem while your chain is on your largest (highest) gear. Not only will you not have to worry about the cage hitting or being too close to your cranks, but usually I find that by making it fit with my chain on that highest gear, the other gears pretty much sort themselves out.

For securing the dérailleur to your frame, I typically aim for 2-4 cm above my largest chainring. After fixing the height, adjust your limiting screws on the dérailleur so that the cage is about 2 cm from the outside of your largest chainring and again about 2 cm from the inside of your smallest chainring (the first gear, smallest gear.)

Now, unfortunately (and especially if you're running a Shimano group set, there will most likely still be some noise from the chain rubbing against the dérailleur cage. This is something that most riders just have to deal with. I personally try and keep the noise to a minimum by making sure my chain is clean and lubed well so that it glides through the cage easier and quieter.

Good luck fixing your problem!
