grammar and punctuation

Is the sentence correct from viewpoint of grammar and punctuation:

The computer literacy is also called “computer competency” which means that, to be computer literate, a person must be able to use computers and related technology efficiently.

Without further context it’s not possible to be sure, but I don’t imagine the article should be used at the beginning of that sentence.

Bev, I’m particularly interested in the middle of the sentence “…means that, to be computer literate, a person must…”. Is it acceptable to include infinitive construction putting commas?

The commas shouldn’t really be there.

Thank you!
