Upon further review, it's probably a Southern Tussock moth caterpillar. Apparently, it can sting. I'm indifferent about the bug. Doubt it would bother anything you're trying to grow. Here is a link that might be useful: http://www.floridanaturepictures.com/butterflies/southern_tussock.htm

Ichneumon wasp, considered beneficial. It is an accidental visitor in your home, unfortunately. That long 'stinger' is actually the ovipositor, used to insert eggs into host insects for the parasitic relationship. Some Ichneumon species can sting and other don't, can't help you there. But I sure wouldn't be alarmed by this creature.

Perhaps leaf hopper, but picture is awfully blurry, as said.

If there are few you can pick them off or wipe them off with rubbing alcohol. That is a second instar, so easy to remove. Watch out for more. tj
