Tips about the forums...yes ask any questions that you have and using the search engine is a wonderful feature. So many topics have been covered so completely and the threads are so informational.
Also make sure to check out the PSE forums to see what is going on in there.
Oh yes you can use anything together that you like as far as kits and elements, they are your LO's and should be made how you like them and yes just credit the designers that you use items from.
Other then that, just have fun!!
