Let's take a look at your questions.
1. The combination of the Jungfraujoch and Interlaken is perfectly suitable for one day. Note that Interlaken itself may not be that interesting. You may prefer exploring the direct surroundings, for example by a boat trip over Lake Thun or Lake Brienz, instead.
2. Some of our favourite scenic trails in the Jungfrau region are listed here. Mind that not all of them will be accessible yet in early May, due to snow. It can't be predicted which trails will and will not be open. You'd best inform at the local tourist office once you're there. Shifting base to Grindelwald is an option, but Grindelwald is pretty close to Interlaken, so it's not a necessity. Generally, if you prefer a central location, Interlaken is best. If you prefer to stay closer to the mountains, Grindelwald would be a better option.
3. A day trip to Titlis will make for a long day, but it is possible. There are alternatives in the Lucerne area that require less traveling time though, such as Pilatus (and other options in the immediate surroundings of the Jungfrau region). The timetable helps you to plan all details of your day trips.
4. You'd best take a look at the Interlaken Tourism website for trusted paragliding companies, and contact them to inform about the options.
5. The Glacier Express doesn't run between Bern and Chur. The route is described at our Glacier Express page. If you want to enjoy a (large) part of the route, you'd have to get to Zermatt, Brig or Andermatt first and board the Glacier Express there. You can travel as far as St. Moritz and do the Bernina Express route from here (the leg Chur-St. Moritz belongs to both the Glacier and the Bernina Express). This all would be way too much for one day though. If you're interested, I suggest you spend an extra night in Switzerland, for example in St. Moritz.
6. The timetable I mentioned shows all options. The one via Chur and Sargans makes most sense.
Once you have an itinerary, I suggest you look into rail passes to save money.
Does this get you started?
