should I change? Part Sun, Part Shade location. The sunniest part of the yard.
It sounds like you have too much nitrogen, and not enough phosphorus and potassium. I would test your compost and potting soil (your potting soil is likely the culprit) for excess nitrogen.
If you are going to use compost, then I would supplement with a low nitrogen mix. Seed starting mixtures are great for this purpose.

How soon after winter can I remove leaves and mulch that are protecting plants during the winter months. Spring is near but in the north we often get frost so I dont want to remove to soon.
That depends on the exact plants in question, their tolerances, and how far out of their native range they are. Native plants require no extra protection, so will not need to be uncovered since they will not get heavy mulch.
Each other plant that is non-native, or requires extra mulch will need to be removed according to when each breaks dormancy. This will be plant specific. Generally, you will want to do this as soon as possible, as well.
Make sure to keep it handy just in case you experience a round of cold weather, later.

How dangerous is a two-hour period of 31 degrees in mid-April when tender shoots are out?
It depends on the type of shoots and if it can handle that temperature for any amount of time, unfortunately.

Our cotoneasters look as if they could burst into leaf very soon. However, at night the temperature is falling 3 or 4 degrees below freezing. Should I treat against oystershell now? Or would it be advisable to wait until there is no risk of frost at night? I look forward to hearing from you. Thank you very much.
You can apply horticultural oil before bud break in spring to suppress any existing scale. The temperature shouldn't make a difference.
We got too much rain and the backyard was underwater. The water receeded by the next morning. Only part of my garden was underwater (see picture). Can I still eat these vegetables? There is lettuce, basil, green beans, zucchini, carrots, cucumber. Thanks.
As long as the veggies look palatable and dried out they should be OK to eat. If the lettuce got too much water, it may be too water soaked.
