Tomato Help Needed

OK all you experienced gardeners, I need help! I found my first ripening tomato today, and also found these. Can I get rid of these guys? Any suggestions would be oh so helpful. In my arsenal already are insecticidal soap, diatomaceous earth and neem oil. Would any of these be helpful to me? I've been so careful of these tomatoes, and they've come through so much. I've got so many of them near ripening. I hope I don't loose them all now!

Happy Little Peas and Onions, and VERY Unhappy Tomato Plants

Green is said to be a very relaxing color. I'm sure this is true. When I was a new mom and had trouble letting my milk down, I would look at my houseplants (it was April). It really worked! I could relax and let it flow. It's still very relaxing for me to look out the window, or be outside near the garden. I especially love looking at the peas and onions this time of year. The green is so brilliant and beautiful.
That said, I'm not enjoying looking at my tomato plants. Especially the cherry tomato. It has issues, and I don't know how to help. Is it just too cold here? It's potted and placed on the sunniest side of the house. It's still tiny and looks sick. When I potted it after picking it up at the nursery I watered it with a diluted manure tea that I picked up at the local dairy. That was about 2 weeks ago. I hoped it would help it thrive, but...
I never have had success in getting any tomatoes to ripen here. I did see Mama Pea's set up. Wow! What sweet looking plants those are! I guess I'll have to do some serious work if I want tomatoes like hers!?! Beautiful, Mama Pea! If you want to diagnose my sick tomato plants, please see the photos following. Mama Pea...Erin...? THANK YOU! ;)

Happy looking peas.

Happy onions. What do you think, Erin? Are they OK?

healthier top growth

Sickly looking bottom growth that seems to be spreading toward the top of the plant. The Early Girl planted next to it seems to be slightly affected by whatever it is too. The leaves turn a very dark, spotty green and then the edges begin to dry up. It is well watered, though, so I don't know. That's about all I know about gardening at this point. Weed, water, fertilize...
