You can mix radiators with baseboard in one room, or have baseboard in one separately zoned room and radiators in another if each room is separately controlled by zone valves. As a two-pipe European system is made for that purpose, that's Ok.
Putting baseboard in one room and cast in another on one single series loop so the water passes from room to room can make the rooms different temperatures as the reaction time between radiators and baseboard is much different - not good.
A radiator heats the air by rising from bottom to top so feeding hot water in the top and out the bottom heats the air as it rises through the radiator. Don't forget the manual air valves on the opposite side of the radiator from the feed.
It is ordinary to run the water lines up the sheetrock or lath side of the outside walls, but not against the outside sheathing. 1/2-inch tubing from the mains will do for 2-pipe European systems.
