No credit card required
Browse credit cards from a variety of issuers to see if there's a better card for you.
See if you can negotiate a pay for delete with the Dish Network collection company and possibly look into opening a secured credit card or 2 so that you have a couple more positive tradelines. Not sure how to handle the Medical collection but someone else here will have solid advice there too. Good luck!
For unpaid medical debt that is reporting on your CR:
1. Call the OC and see if you qualify for Charity Care
2. If not then ask that they recall the collection in exchange for full payment
3. Send the reporting CA a PFD offer
4. Google the HIPAA Process and contact its creator for help
