okay. Lets break down your situation,
1. If you have EAD throught asylum, just go ahead and renew that, no need to worry about TPS EAD
2.With your asylum case pending, TPS has very less to do, and again, if you feel safe with TPS, you can apply it on your own (no need of attorney). Apply TPS only, not EAD
3. Life is too short to stay in Dilemma, so relax and wait for asylum interview for another year or more. Its already complicated with asylum case pending.
