Edit Magento Product Display Page

I have a live Magento store (1.7.0.2) which has a modified 'Blanco' theme. I am looking to make two changes to the Product Display pages but although I have been able to do some of the work on the site myself these two go beyond my programming ability! Job One: I want to display a breadcrumb for each category the product is in. So for example if I have an Adidas men's gym T-Shirt which is in 3 categories then it would be displayed like: Designers - Adidas Men's - Clothing - T-Shirt's - Gym Men's - Clothing - Sportswear I have attached a screenprint from another online store to give an example of it, I would not want the arrows but would want the final category in bold like that. Job Two: I currently have the product page displaying an accordion menu to display the description, size information, delivery information and returns information. The description option is displayed when the page loads which is how I want it. However I want this accordion editing so only one opens at a time, eg. if someone clicks to view Size Information then the Description section will slide shut. I also want arrows on the options which toggle open/closed depending on if that section is displayed or not. I have attached a screen print from another online store to give an example of it. This is how I would want it styled with the horizontal lines and location of the black arrows. That is it, not massive jobs but I am looking to develop the site a lot further over the following months with some much bigger jobs planned. So if I can find a reliable and good freelancer I would look to work with them again.
