I have a few comments
1) You need to make sure you have a few relationships that are very strong for getting Letters of Rec. The only alarms I hear is that you quit on a lab because you weren't getting good results. Therefore, will these people still write you a rec? All grad programs require 3 recs in Clinical Psychology
2) I'd actually disagree with you regarding all of your premed ECS are relevant for clinical psychology. I could be totally wrong, but in premed boards and "How to get into Medical School" I always hear a lot about service oriented things, volunteer hours, social responsibility stuff. I think this is really less emphasized in clinical psychology programs. It might be a great thing to have, but I think it will contribute less to your application than if you were applying to medicine.
3) My best advice is that you get research experience. I know you said you don't like research, but if you want to get into a Ph.D. program in Clinical, they are generally always looking for research experience. I'd find a lab you can volunteer in for at least a year, maybe longer. If you start now, you can probably get some nice experiences before you apply next Fall.
4) Start to learn your field. Shadowing sounds interesting, but you can also just start to read papers in the field you want to enter, and learn who the key players are and the big concepts.
