Immigration Site

All the different comments and info a person reads online can become quite confusing sometimes. i just want to make sure Iґm on the right track when I send off our papers for I-130.
I am an american citizen my husband is german, applying for husband, we are both in Germany....
1. I-130 q.10? does this have to be filled out? (Where am I suppose to find it?)
2. G-325A forms? Two of them but the are no extra cost?
3.What costs are coming yet? It should not be that long of a waiting process, or...?
4:Thanks alot for your replies.

p.s. I have read and read and read and now Iґm just double checking
