Our route is as follows: Warsaw - Gdansk - Torun - Warsaw - Radom - Lodz - Ostrow Wielkopolski - Katowice - Krakow - Warsaw
3) What is the highest speed limit on the highways? And do the police fine the faster driving people a lot?
Highways (blue sign with a viaduct at the beginning, blue direction signs, mostly paid) - 140 km/h, expressways (almost the same standard as highways, blue sign with a car at the beginning, green direction signs, free of charge) - 120 km/h. Normal roads inside built-up areas (marked by white signs with black town buildings shape) - 50 km/h, apart from the nighttime between 11 pm and 6 am - then 60 km/h. Outside: if they have one roadway - 90 km/h, with two roadways - 100 km/h.
I understand that you have to visit all these cities and towns.
By DK (for "droga krajowa" - "national road") I will denote the main roads (white numbers on red background), by DW ("droga wojewódzka" - "province road"), if I will need, the secondary roads (black numbers on yellow background).
From Warsaw to Gdańsk I would go by DK10 to Toruń and then A1. If you prefer highways, you may choose A2 to £ódź and then A1. It would take probably slightly more time, and definitely more fuel, but at the route Warsaw-£ódź-Toruń highways are free of charge. For the section from Toruń to Gdańsk you will have to pay 30 PLN. If you don't have to pay, you may choose the DK91 instead A1. It's the old DK1, from before the construction of the A1. It's also a good, wide road, but with only one roadway and many built-up areas. It's definitely slower and less comfortable.
Back to Warsaw through Toruń - the same route.
From Warsaw to Radom - choose DK7, whose big section is now an expressway S7.
From Radom to £ódź I would choose DW740 to Potworów, then DK48 to Tomaszów Mazowiecki, and then DW713 to £ódź.
In £ódź there is many road construction works, so be careful. For the best, tell us where you accurately have to go in £ódź, we will give directions. Driving in £ódź is quite tricky now as a lot of streets is closed for traffic.
From £ódź to Ostrów Wielkopolski - To Sieradz you have a new expressway, S8. Then you have to leave it, drive DK12 to Kalisz and then DK25 to Ostrów. Unfortunately you have to go through a city - I mean Kalisz.
From Ostrów to Katowice - you have a road DK11. It may be quite crowdy, but it's probably the best choice.
From Katowice to Kraków - the most comfortable will be the A4, but it's also paid, like the A1 from Toruń to Gdańsk. You will pay 18 PLN. As a free alternative I may recommend DK94.
From Kraków to Warsaw the best will be probably DK7 through Kielce and Radom, whose parts are modernised to the expressway standards and marked as S7. You don't enter Kielce at all as there is a bypass road; the road through Radom seems to be straight and simple.
You may see practically all the roads on Google Street View, it covers Poland very well. I recommend it especially in terms of how to go through cities, and how the places where you have to turn left or right from the main road look like. Unfortunately it don't have the newly built roads (S8 from £ódź to Sieradz) and it won't show the current road interruptions in £ódź.

These are the main networks, I didn't check the virtual operators. For more details you have to search the Polish versions of the operators or find a selling point of the specific network where somebody is able to speak English.
You may check also:
play.pl/en (all the information are much more readable than in the Polish one, even for me, although it is lacking of details, for example that in "Lubię To" the "free" data transfer has limited speed so that it's practically impossible to use it)
I can't unfortunately find English versions of other operators webpages.
