If you are not leaving the US, your expired visa will not pose a problem. The expiration date of the visa is the last date on which you may show up at the US border and seek to be admitted to the country. The expiration date has no effect on the allowed length of your stay.
I can't say for sure whether you will have problems on other grounds, however, because I do not know the implications of being "without status" or of having a pending application for permanent residency.
If it means that you should avoid coming to the attention of immigration enforcement officers, then you should consider whether your travel will increase the risk of that happening. I would guess that the increase would only be significant if you plan to be travelling near enough to the Mexican border that you encounter internal immigration checkpoints.
If, on the other hand, your pending application for permanent residency means that you will have no fear of coming into contact with immigration enforcement officers, then you should have no reason to avoid traveling.
