I want to plant some coneflowers and some other easy to take care off flowers like this. I am planting these because I need ladybugs how close to my vegetable garden do I need to put them?

I've never heard of planting for ladybugs. They go where the bugs that are their food source are. They can be bought for release as beneficials , and released in the garden. I tried it once. They bred like crazy and left

Lady bugs also feed on nectar
i am into mostly herbs so these will attract your ladybugs
yarrow, dill, fennel; tansy, calendula
I suggest planting the herbs along with your veggies , my herb bed is in the middle oof the garden

...as for flowers cosmos and coreopsis are good choices and they also attract butterflies.

I saw one on my bush bean bed today, but when I had a huge borage there were everywhere. I'm now letting some borage to take off, only the attractive ones, not the unruly ones.

Which would those be? I planted some seeds once about 10 years ago. Now, I spend my spring eliminating Borage seedlings...leaving enough for the bees. Now, I'm in eliminating mode again, as they are going to seed, and not so pretty.

You can tell, some look aggressive like they are going to take over my yard, I just want the not aggressive looking plants. I've been removing them. I kept some.
