Ven's sentences with the infinitive after "instead of" can be considered correct according to this entry in Quirk*:
"Instead of" may be classified as a marginal preposition....it can have an infinitive clause as complement: ˜It must be so frightful to have to put things on in order to look better, instead of to strip things off.' (Margaret Drabble: A Summer Bird Cage)
Although "instead of" + infinitive has been attested in good written English, many would here prefer....instead of stripping ..(which, however, would spoil the parallelism with to put that may have motivated the use of to strip here."
I guess I am one of these who "would here prefer," but Quirk's descriptions are far more authoritative than mine, so I stand corrected.
In the first sentence above, again, the sentence could be considered this way:
"¢ The Federal Arbitration Act allows businesses to require workers to agree to take any disputes with the company to arbitration instead of (taking the company) to court (from CNN)
Actually, in this sentence, "to court" is not an infinitive, but an idiomatic expression in a prepositional phrase, "take someone/ something to court."
The second sentence, though, exemplifies the explanation from Quirk.
