As to the issue of time, do not feel that you have to do all disciplines to the extent of doing the disciplines for set inviolable prescribed times. Get the proper no more and no less amount of needed rest and then apportion the remaining time to the disciplines you have set out to accomplish.
As for the clothing: just find light colored clothing without company logos or other distracting emblems. Find clothing that is comfortable and hypoallergenic, especially organic and free of synthetic or harmful chemicals as possible. Cotton or other natural materials are useful to maintain comfort, temperature and ritual purity.
