ToC style, using ToCloft

I’m preparing my thesis in LYX. Previously I asked a question about article class, but then I’ve found that it would be better to use report class instead. I use a tocloft package and code looks as follows:

documentclass[14pt]{extreport}
renewcommand{familydefault}{rmdefault}
usepackage[LGR,T1,T2A]{fontenc}
usepackage[koi8-r]{inputenc}
usepackage[a4paper]{geometry}
geometry{verbose,tmargin=2cm,bmargin=2cm,lmargin=2.5cm,rmargin=1.1cm,headheight=17pt}
usepackage{fancyhdr}
pagestyle{fancy}
setcounter{secnumdepth}{1}
setcounter{tocdepth}{1}
usepackage{float}
usepackage{units}
usepackage{textcomp}
usepackage{amsmath}
usepackage{stmaryrd}
usepackage{graphicx}
usepackage{setspace}
usepackage{esint}
usepackage{subscript}
onehalfspacing

There are 2 points still looking not like they should.
First one- the header of ToC is not centered. However I used a command renewcommand{cfttoctitlefont} that should provide centering.

And I need the chapter (‘Глава ‘) name to be followed by dots just like section name.

How can I edit these?
