Some minor edits on live Magento site

This Magento site has been heavily modified, with some core files being edited (not ideal, but it has been inherited like that).

There are a couple of code changes needed:
1. New bundled products are not displaying a price and the "add to basket" button cannot be clicked - existing bundled products are fine.
2. New bundled product prices are not showing in the right font in the category view.
3. Hide one line of text on Basket page.
4. One section of wording (product list) in the PDF invoice/packing slip needs moving down a little, and the gift message needs centering.
5. Edit two identical lines on the checkout.
