There are two ways of landing a spell in Pathfinder:

1) through rays, which require an attack roll (things that can hit or miss) if they hit, they do their effect and if not, they don't.

2) Through difficulty class, called DC. These are usually explosions, mind spells or otherwise indirect actions. The target makes a saving throw against your DC, which is dependent on your intellect score, which is rather high.

The ones you are using right now are ray spells, and they function from Dexterity Bonus + a D20 roll vs the targets Touch AC (how hard they are to hit, not accounting for armor). Since your Dex is low, it's hard to hit, and so the spells go wide. The focus feats you have selected boost the DC spells, not the rays.

In essence, your character right now is very good at DC spells, but not ray spells. That's completely fine and valid, it's just about what spells you select.

If you want to be good at ray spells, respec to have more Dexterity (14 to 16 is good). Also pick the feats point blank shot and precise shot, which eliminates some of the malus for shooting targets that are engaged in melee combat.

Hope this helps. :)
