I already applied TPS and currently on my grace period what should i do next? inform my current DSO or what ? If i didnt transfer to another college do i will be out of status or my SEIVES will be active due to TPS.

If you just apply for TPS that is not going to keep your SEVIS active. Even if you apply for TPS, you have to Maintain your F1 status. Since you are in your grace period you have less than 2 months to transfer to another school.
Did you apply for OPT?
Go talk to your DSO and let them know you have applied for TPS and how can you keep your SEVIS active during that time. If college reports to USCIS that you are not a full time student then you will be out of status.
