1) Can work items be shared across projects? For instance can
multiple, related projects be set up so that work items can be
accessed in across each project.

Each work item belongs to a single project area, but you can link work items in different project areas of the same repository and freely navigate between them.

2) Is the linking between work items dynamic, such that updating one
could update the information of the other. For instance have a
parent work item tie down to multiple tasks. When each task is
completed the parent work item's hours completed gets updated.

Plans and Stories have progress bars showing an aggregation of the work done.

3) Can you split work items across multiple iterations? For instance,
if part of a work item was completed in iteration #1, could you split
that work item so that the remainder of it is scheduled for iteration
#2?

You could duplicate the work item (see context menu on work items) and close then close the original as fixed for the current iteration while planning its copy for the next iteration, but you would have to split the estimated time manually.

4) What is the best way to link work items to design artifacts?

You can drag&drop other Jazz artifacts into the links tab of the work item editor or add a Related Artifact link using an URL. Alternatively you can also drag&drop Jazz artifacts into the work item's description/comment field.
