I'd recommend you go to the ONP Visitor Center in Port Angeles; they can help you find the best hikes for you, give you the most up-to-date advice (conditions can change quickly in March), and answer your questions. Hurricane Ridge, up the hill from the visitor center, will still be buried in snow, but if it's a clear day (iffy in March), the views are incredible. It can be clear one hour and socked in with clouds the next. There are monitors in the visitor center showing the current web-cam views, so you know the conditions at the top before you decide to drive up. The Lake Crescent area is close to Port Angeles. There are a variety of hikes there (scroll down to see a chart of the trails.)

Similarly, the NPS website has details about the Hoh area, including a list of trails in that area.

At Rainier, the Nisqually entrance up to Longmire is open every day (unless there's an active snowstorm). The NPS page about Longmire lists some hikes there. The road from Longmire to Paradise is only open on weekends this winter. There's currently 10 feet of snow at Paradise, so there won't be any hiking there until summer.
