Rosemary getting spots and 'visitors'

Transplanted nursery rosemary to a giant pot on my deck. Going well so far, but I'm noticing little golden colored "polka-dots" on many of the lower leaves.

I plucked one of the worse offenders and did this trick whereby I turn my binoculars upside down and can kind of use them as a makeshift magnifying glass. Here's what I found:

- Aphid-looking creature, looked like it was laying eggs. There were all sorts of similarly-colored balls on the leaf near it.

- Dark little (reddish?) round-shaped bug crawling around- maybe a rosemary beetle? No, upon further googling, those look big. This one is teeny- you could fit 4 or 5 of them across on a rosemary leaf

- amber-colored balls along the side of the leaf

Before I freak out, considering ALL THIS was on the first leaf I plucked, any idea what the spots may mean? The "visitors"? What's my best solution for keeping it relatively bug-free?

Coming back to say I stopped by the nursery to describe my spots and actually found the same spots on their rosemary plants, so I showed them and they said the spots are due to thrips. They sold me some organic Dr. Earth spray (the kind that has different oils & such in it) so I came home and soaked the plant and moved it into the shade. Hopefully that will help with all of the "visitors"!

Keep it in the sun.

Tomorrow it'll be back in the sun, but the spray directions said not to have it in the sun right after spraying or it might get "sunburn" : )

Neem is also a great product to kill insects that damage plants. Its organic and has been used in many pesticide and even fungicide applications.
