Fixed a few design aspects on our current website

Hello, I need a programmer who can change a few design elements on our website and would also like to know where I can do this in the future. Our website is: www.sadvidyafoundation.org
1. HOME PAGE
a. Place the NEW logo with the sanskrit letters, at the left top (New logo in media Library)
b. Move text which is after the main cloud image - LIFESTYLE AND YOGA Combining lifestyle with a dedicated practice etc.., Place this text (Keep the same font in lower case) on the home page cloud image and have an arrow or "scroll down for upcoming events"
Q. Why are the last two images in the circle blurry? How can this be fixed?

2. In the drop-down menu:
A. JIVANA CLASSES:
1. Move the text 'Combining 'lifestyle' with a dedicated practice etc...' in the main banner under the title. Keeping the same font in lowercase.

B. YOGA SUTRA CHANTING INSTRUCTION
1. Move the text 'Chanting is a doorway to deepen etc...' in the main banner under the title. Keeping the same font in lower case.2. Why are the images of the Sanskrit letters in orange circles blurry?

C. AYURVEDIC RECIPES
1. Move the text 'Ayurveda is to the body, as Yoga, etc...' in the main banner under the main title. Keeping the same font in lowercase.
2. Also here, the images do not come up sharp but instead blurry. Why is this and can it be fixed?
3. Have the title of each recipe on the image without having to hover over it.
