No these things are not forbidden. They were forbidden in the Jewish law, But Christians are not under the Mosaic law anymore:
Galatians 3:24:
Therefore the Law has become our tutor to lead us to Christ, so that we may be justified by faith.
Jesus fulfilled the law and we are in a sense out of school. We do however need to examine what each law was trying to teach us. Laws about usury were to prevent people taking advantage of each other. laws on pork were to keep us health, because pigs at that time where dangerous to eat. This teaches us to respect our bodies and care for them.
Here it is in the jewish law:
Leviticus 11:7-8
And the swine, though he divide the hoof, and be clovenfooted, yet he cheweth not the cud; he [is] unclean to you. Of their flesh shall ye not eat, and their carcase shall ye not touch; they [are] unclean to you.
Deuteronomy 14:8
And the swine, because it divideth the hoof, yet cheweth not the cud, it [is] unclean unto you: ye shall not eat of their flesh, nor touch their dead carcase.
Isaiah 65:3-4
A people that provoketh me to anger continually to my face; that sacrificeth in gardens, and burneth incense upon altars of brick; Which remain among the graves, and lodge in the monuments, which eat swine's flesh, and broth of abominable [things is in] their vessels;
Isaiah 66:16-17
For by fire and by his sword will the LORD plead with all flesh: and the slain of the LORD shall be many. They that sanctify themselves, and purify themselves in the gardens behind one [tree] in the midst, eating swine's flesh, and the abomination, and the mouse, shall be consumed together, saith the LORD.
laws on usury can be found here: Exodus 22:25-27, Leviticus 25:36-37 and Deuteronomy 23:20-21.
