As Teremsi said there is no such thing as standard division. You have 3 division lists in Deluge, and 2 more in PDF and every division can have from 3 to 5 regiments. You can have pure swedish divisions and with allies like Commonwealth, Transylvania and Brandenburg. Lots of options.
First, Reiters. Lots of them. For a start 12-22 bases of unarmored and 8-12 armored. They are base of every division. There is never too much Reiters.
Second. A Box (or better two) of infantry national/mercenaries new type. You may need more, maybe even old type.
Third. You may like dragoons. 8 bases are good for a start.
Fourth. Cannons. 2 medium and 4 light guns is all you need. Don't forget transport wagon with ammo for them.
Of course High Command is a must.
With that you can start to create your division(s). After few games you will know what more you want. I.E. Brandenburg allies are very powerfull especialy 12 bases of armored veteran Reiters
