Tabloid-friendly nature of their work

1. Does "In both cases" mean "In the case of both Damien Hirst and Tracey Emin"?

2. Does "tabloid-friendly nature of their work" mean "they used collages of tabloid magazines in their works"?

3. Does "along with that of Sarah Lucas and Marcus Harvey" imply "similar to Sarah Lucas and Marcus Harvey"?

Context:

In reconfiguring the advertisements in paint and recontextualising them as works of art, Koons rescued them from their everyday circulation and held them up at a critical distance for new scrutiny – as Marcus Harvey and Sarah
Lucas were to do with their appropriations from tabloid journalism...

... Damien Hirst and Tracey Emin have become the most infamous representatives of this new generation of artist-celebrities. Both have achieved lasting status as media stars and both have been key to the branding of British art in the 1990s and the consequent recognition of contemporary art as cultural capital. In both cases, a brand image was initially built on the tabloid-friendly nature of their work which, along with that of Sarah Lucas and Marcus Harvey, was easily puffed up into sensationalist news. In addition, Hirst and Emin both showed entrepreneurial and self-promotional talent of their own in the early stages of their careers, partly following the lead established by the artists Gilbert and George, who took pains to become publicly visible through live performances that intruded on other events both inside and outside of the confines of the art world in the early years of their career.
