Will it impact my ability to get future credit cards or other lines of credit like loans, etc.?
As long as there's no adverse information associated with the account such as a 30 day late, etc... no, the account will stay on your reports as a positive closed account for up to 10 years.
There's always the possibility they don't close it too. The biggest thing is to get it paid off so it stops negatively impacting your scores due to the high utilization.
