To answer your second question, when ions get larger in an HX acid, the length of the bond between the hydrogen and the ion gets longer. Longer bonds are weaker and more easily broken, allowing more H+ ions to be broken off and released into the solution to create H3O+ ions. This gives a higher concentration of H3O+ ions, giving a smaller pH and thus a more acidic solution.
As to tricks to distinguish strong versus weak acids/bases, I would suggest memorizing the strong acids and bases because they are only a few of them. Also, learn the trends that increase or decrease bond strength (i.e., number of Oxygen atoms, atomic radii, and electronegativity)
