Hmm.. strawberries! Interesting experiment.
Tomatoes rock. I have them under a 600 watt hps, they just seem to like the super bright 12/12 light more. Be careful with your nitrogen! Itll get viney with few fruits if you overdo it.

As for strain of tomato, look for someting indeterminate (constant tomatoes, versus a boom of them) and crack resistant. Blossom end rot can be avoided by giving some calmag (or other source of calcium) when the flowers are setting.

DreadedHermie, Id like to hear more about peppers! Theres nothing I love more than a fresh jalapeno.
