I'm really not an expert on US carriers so I'm sure there are others who have better insight into this.
I also think there is a sticky somewhere about status matches and where you should send your documents.

All FF-programs have their pros and cons. The US programs tend to have better recognition and also offer many possibilities for free upgrades.
However if you are gold in a US program you usually don't get lounge access other than if you fly outside the US or on an international flight ex-US.
Lounge passes within the US are available for purchase, the fact that you are gold makes no difference other than that you get a discount on the lounge pass.
This is a major difference from for example SAS gold where you get lounge access everywhere, including when flying domestically within the US.
