Start with Belgium, they are by far easy.

Once you have won the rebellion, go on the offensive.
- usually I invade the dominican republic and place ships and a LARGE garison, basically because it gives you good resources and you have a large number of men to take andvantage of a war between england and USA. after the smoke settles I usually also have captures Florida
- My second objective is always Madagascer, it might take a little time, but I find it is well worth the effort.
- Thirdly I would invade a province just left of the Indian subcontinent and then work my way into to other independant states.....

Back at home, it depends on what type of game you want to play as to what items you need to research, usually I try to go for an industrial based.....

Build railways and factories where ever possible to match to needs of the homeland provinces...

BTW if you go over to the Victoria forum, you will find links to loads of differnt walkthroughs and advice, they are all very useful and worth a look.
