Return on Capital Employed is Net Income divided by Equity + Debt employed. So the difference between ROE and ROCE is that ROE factors in only the Equity Capital bur ROCE factors in debt also. So a debt laden company's ROCE will be lesser then ROE due to a higher denominator in ROCE.
While ROE and ROCE are used to measure how optimally capital is being deployed, IRR is used to measure the feasibility of projects or in other words the returns from a project. ROE and ROCE only take into account the Net Income and net income does not take into account Capex expenses like new machinery etc. IRR is calculated using a company's FCF (Free Cash Flow - explained in later modules) and hence is a better representation of the actual returns from a project.
Now, Networth = Assets - Liabilities. It is also = Share Capital + Reserves - any carryforward losses from P&L. Basically this means that the share capital is reduced by previous years loses or increases by profits in order to get to net worth. In Dominos case, since it was previous years loses (page 12 of http://www.sebi.gov.in/dp/jubilantdraft.pdf) the net worth is lesser than the share capital.
