What type of herbs are you talking about? Most herbs are very forgiving, so you'll probably be alright no matter what you do.
For things like Basil, Thyme, and Mint, I like to just pinch the top bunch of leaves off each stem when I use them, so the plants end up nice and bushy. For things like chives, parsley, and cilantro, I cut off as many stems/leaves as I need (and always leave a few so it can regenerate).
I'm not sure about planting in your zone. Here in 4/5, I would feel comfortable planting beets for several more weeks yet. If you have the seeds, it is worth a shot.
