1. Do DS shuttles run late to pick up after
MNSSHP and
MVMCP or would we have to Uber/Lyft?
In the past the Disney Springs Hotels buses have only operated during normal theme park hours. If you are attending a special event after normal hours, you'd be responsible for getting yourself back to your hotel.
2. How close can Uber/Lyft drivers get to the park entrances?
I don't use those companies. Somewhere else may be able to answer your questions. Or, visit the "Everything you nnated to know about Uber/Lyft at WDW" thread on the Transportation forum:

3. I read that the DS shuttles start running 60 minutes before parks open. Is that enough time to get a good place in line for rope drop and am-emh?
I'm a night owl, so I've literally never been to a theme park for rope drop. Other people might be able to answer.
That said, one of the drawbacks of the Disney Springs Hotels bus system is that each bus visits two theme parks. If you're visiting the second park (typically Disney's Hollywood Studios and Disney's Animal Kingdom), you won't arrive until about 35-40 after you leave the hotel. In that scenario, you will arrive before the official opening time, but not by much.
4. Are there any markets within walking distance for some quick groceries for breakfast or sandwiches?
There is a shopping area called Crossroads that is a short walk from the DoubleTree Suites. (Bing Maps says about 0.5 miles/9 minutes walking.) There a number of different restaurants, including fast food/fast casual options that are priced much cheaper than restaurants on Disney property. I'm a big fan of Perkins, which is a regional chain similar to Denny's. They are open 24/7.
There also is a grocery store called Goodings. In my experience, it's priced higher than normal grocery stores because they know lots of visitors don't have cars. Be sure to check the products you buy. On my last two visits, I've seen them trying to sell products that are past the "Best By" dates on the packaging.

5. Approximately how long is the walk from the DS shuttle dropoff at the parks to the parks entrances? Would we need to use the trams?
Read post #24 in this thread. In that post, I provided aerial photos of the approximate location of the bus stops for the Disney Springs Hotels buses in relation to the main entrances of each theme park (or the Transportation and Ticket Center for Magic Kingdom). In every case, the bus stop is within a short walk of the entrance.
There are no opportunities to use parking lot trams, as those operate in different areas.
...especially for what we can get at the Doubletree vs an All Star room
The DoubleTree Suites is my favorite Disney Springs Hotels. In the many stays I had over the past few years (easily 80 nights), I've never had a major issue. Any minor problem (like a dead TV remote or safe that wouldn't open) were fixed with a single phone call. And, the suites there are approximately twice the size of a Disney All Star Resort room.
