1 & 3 will need the source code for the layout and theme layers - probably easiest to just put them in a pastebin and drop the links here.
2 I think maybe a DW-side issue - basically, earlier this year we modernized some of the Javascript used in journals, which caused a bunch of the automatic stuff to stop working in very old core1 layouts. I know we have a fix, but I forget if it's live and/or there's something users need to do - will follow up with the dev who wrote the fix and let you know.
4 looks like it'd be something easy to fix in the layer source code - basically add style="max-width:100%" to the image tag.
