Re: VSEPR angles
Personally, I try to kinda visualize all of the basic shapes (tetrahedral, trigonal pyramidal, trigonal bipyramidal), and in these shapes, all the angles are pretty easy to deduce once you have already kinda visualized the name. The remaining bond angles are usually just less than the "base" shape, such as tetrahedral, which is 109.5, but shapes like bent are less than 109.5.

Re: VSEPR angles
VSEPR shapes that have lone pairs of electrons exert more repulsion on the atoms around the central atom, so they will have smaller bond angles. For example, AX2E2 has a smaller bond angle than AX4, since it has 2 lone pairs and 2 bonding pairs and therefore more repulsion when compared to the latter, which has 4 bonding pairs.
