Hi c&c, 'Maynard' is listed as a self-fertile variety but as cherries tend to flower very early in the year, there are often few pollinating insects about so hand-pollinating is a good idea. In fact, I do that with all of my fruit trees as most are dwarf. It only costs a bit of time.
All fruit trees need a feed and a few handfuls of fish, blood and bone sprinkled and tickled into the soil in early Spring is all they need. Sprinkle the feed over an area of about a metre diameter around the tree and keep that area free of grass and other plants as these will compete with the feeding roots of the tree (which are close to the surface.) A mulch with compost or well-rotted farmyard manure is also a good idea but don't let that touch the trunk as it can cause problems if it is piled up against it.
As an aside, even self-pollinating fruit trees will crop better if there is another variety in the vicinity, so a getting different cherry but in the same pollination group (Maynard is B) may well help if you have the space for a second tree.
