The relation between gross and net is different than in Germany. The gross salaries might be a little bit less than in Germany but the net salary could be surprisingly high. As an example: In Ireland, 2083 € gross/month is 1803 € net/month. In contrast to that, 2850 € gross/month in Germany equals 1806 € net/month. The salary will be paid monthly, sometimes even weekly.
For those who want to calculate their salary exactly, have a look at services.deloitte.ie. You will see, that the tax load is quite low in Ireland.
As an EU citizen you do not need a work permit to live and work in Ireland. However, it is important that you set up a Personal Public Service Number (PPS Number) for taxes and social welfare. Further information about the PPS Number can be found here:
Public health insurance is not available. In Ireland the majority of the population is covered through private health insurance, which is reasonably priced. For further information on the topic of health insurance we can recommend this website:
