Magento Display Group Price and Tier Price

There are a few things we need to solve: 1) We have a customized tierprice table however it is not working with one of our price changing extension. In the configurable products when simple product is selected the price needs to reflect the change. 2) Both pre-login and post-login as member, the price in category and product detail page needs to be same. Currently it is showing different price. The job is to fix our Tier and Group Price in Magento Category and Product Details page to display the output that we want. You need to be able to do it on our development site & live site, and upon testing if it is working please let us know list of modifications - what have you done as we need to keep a record on customization activity. Also note that we are running a responsive theme. If you need more information to submit a suitable quote please let me know. Please reply *SGMY* to show that you are not just posting message to get the job.
