Help - just took the bongo on a longish drive and left it a hour, went outside and oil is on the floor

- it has sprayed all up the wheel arch and look to have come from the shock absorber, it's due to have all the drop links and bushes replaced next week - should I be buying new shock ? If so do I have to replace both and if so are the ones from this shop the best place to get them ?
Am I ok driving it home ?
Thanks for your help
