For tomatoes, stick to hybrid cherry types for best performance. Mid/large size ones will start dropping flowers when the lows get above 80F or so.
Covercrops- sorghum/Sudan is a really good choice. You can also look at species that need vernalization to set seed. Things like purple top turnips, seven top turnips, winter triticale, etc.
As for heat tolerance, look at specific varieties. For example beit alpha types of cucumbers (bred for the middle east heat). Indeterminate greenhouse tomatoes tend to produce better in heat than determinate ones, etc.
I know nothing, except I'm I'm in a similar climate and my hot peppers and cucumbers are doing well but banana and bell are hurting. It's very strange but may have something to do with pH, maybe? All of my stuff is in the ground and I did very little prep.
Perhaps basil with the tomatoes?
Cherry tomatoes grew fine over the summer. Most things just needed low intensity morning sun then shade afterwards. I planted a couple trees to help out.
