I forgot to mention that aside from whatever updating Software Update tells you to do after you run the Combo, you'll also have to update Safari (because the Combo includes a Safari update that rolls your current 5.1.10 back to an earlier version).

If you're wavering, I strongly encourage you to run the Combo; your systemic issues suggest that systemic "medicine" may be in order.

Edit: And at the very least, you ought to run Disk Utility > Repair Disk (while booted from another volume).
