The ending dot is Calc syntax and means a float with fraction 0.

Yes, else the Calc result is inserted without change. There is a
formula debugger that shows the formatting steps nicely: "C-c {"
The "+.0" is necessary too to convert Calc integer to Calc float for
some cases as shown in the example tables here:
http://orgmode.org/worg/org-faq.html#table-float-fraction
All together:
#+TBLFM: @4$1=@2$1+@3$1 +.0; f-2::@5$1=vsum(@I..@II) +.0; f-2::$1=$0 +.0; f-2
This is what I recommend just in general and what I do always myself
as a habit because it can deal also with higher precision or the case
when those of the fields resulting in an empty string should remain
empty instead of a "0.00". If you don't want to be prepared for all
that, for your current example you can still use just
#+TBLFM: @4$1=@2$1+@3$1;%.2f::@5$1=vsum(@I..@II);%.2f::$1=$0;%.2f

For an explanation see the URLs to the Calc manual mentioned here
http://orgmode.org/worg/org-faq.html#table-float-fraction
after "For f3 and f-3 see `d f' (`calc-fix-notation')".
