does isothermal always mean:
• constant temperature
• ∆U=0
• so: q = -w
or is that just in specific cases

Yes, isothermal processes always constitute a constant temperature! It follows that ΔU = 0 because for ideal gases, the change in internal energy is dependent upon temperature; if T is not changing, neither will ΔU. And ultimately, q = -w.
