Edit: I tried making a MWE, I hope it is correct this way. If not, please let me know!

@Book{fritzsch,

I'm using biblatex and have some issues with citing the way I am required to.

There are three things I need to change, but I am totally lost on how I can do it.

1. The "renewbibmacro" snippet of code (which I found online when I wanted to display the url and the date when the url was seen in footcites too when the author is unknown) also changed that the year suddenly isn't shown on book entries anymore, which was not intended. A book footcite should look like this:

2. I would like the "Stand: urldate" to be displayed after the url and if possible in square brackets , not round ones ()



3. 
   

   What do I need to do so that the last and first name are not separated by a comma in the bibliography and there is a comma instead of a period after the name? Meaning instead of

   
   
   

   "Fritzsch, Harald. Elementarteilchen - Bausteine der Materie. München: Verlag
   C.H. Beck, 2004."

   
   
   

   it is

   
   
   

   "Fritzsch Harald, Elementarteilchen - Bausteine der Materie. München: Verlag
   C.H. Beck, 2004."

   
   

You may want to try the following.

The comma between family and given name is controlled with revsdnamepunct, the comma between label/sort name and title with nametitledelim.

I have modernised the cite bibmacro redefinition based on the current definition in authoryear.cbx. The only difference to the original is the added block

     ifboolexpr{test {ifnameundef{labelname}} and test {ifentrytype{online}}}

       {setunit{addcommaspace}%

        usebibmacro{url+urldate}}

       {}

that prints URL and access date for @online entries without (author/label) name.

The DeclareFieldFormat{urldate} bit takes care of the square brackets. Compare the new definition to the original in biblatex.def.

The DeclareLabeldates make sure that the urldate is not used to populate the label date used for citations and suppresses the 'n.d.'/nodate string for @online entries.
