Learn Swedish: Vi pratar mycket svenska. - We speak a lot of Swedish.

Yes! It follows the standard Subject-Verb-Object order. Vi (we) is the subject in the first position, and pratar (speak) is the verb in the second position. This is the core of the Swedish V2 rule: in a normal statement, the verb always comes second.

Why is there no word for "of" in mycket svenska (a lot of Swedish)?

In English, we say "a lot of", but in Swedish, the word mycket (much / a lot) goes directly next to the noun it describes. You just say mycket svenska. Adding a word for "of" here would be incorrect.

Why isn't svenska capitalized like it is in English?

Unlike in English, Swedish does not capitalize the names of languages or nationalities. It is written with a lowercase letter unless it is the very first word of the sentence.

Could I use talar instead of pratar here?

Yes, you could say Vi talar mycket svenska. Both verbs mean to speak or talk. Pratar is very common in relaxed, everyday conversation, while talar sounds just a little bit more formal.
