I follow the LSU AgCenter website and planting guide very closely for just about everything garden related. Davesgarden.com is really useful for their watchdog section which gathers ratings on different seed companies and nurseries. And the Seedsavers learning page is a very easy to use website that is great for beginners. It’s streamlined and very easy to understand.

For cucumbers, the planting guide gives fall planting dates (direct seed) of 8/1 - 9/15 for South LA, and 7/15 - 8/31 for North LA.

For tomatoes, if you do heat tolerant varieties you can start transplanting those in mid July. If you don't want to do heat tolerant varieties, you could start seeds mid July and transplant mid to late August. I'd recommend doing an "early" variety that way you have a greater chance of a high yield before the first frost.
