The goal is:

1. Put the dots next to chapter
   a) in ToC,
   b) in text

2. Get left marking work correct, meaning – I want a name of chapter, number of a chapter [with dot], but without a word:"Chapter"

3. Add dots from chapter to the page number in ToC,

4. Enumerate style change: from native to dark square with bold number inside

Answer 1

Below there's a possible solution: the tocloft package was used for 1)a) and 3). A redefinition of \chaptermark solved 2). A redefinition of \labelenumi using \fbox solved 4). Adding a dot after \thechapter in the already existing definition of \@makechapterhead solved 1)b). The code contains some comments showing where the changes were made:
