No special requirements. Just buy a new asana and keep it aside only for Japas and poojas. Sit on the floor on the asana and not on a height. Try facing East or North-east while doing Japas. In case you feel the surroundings are not so clean, chant this stotra 11-21 times before proceeding for any Japa.
"
Atineela Ghanshyamam Nalanayit Lochanam, smarami pundarikaksham ten snaot bhavamyaham". Recite this also while you are taking bath. This is for Atma Shuddhi.
When you recite SVS, Imagine Lord Vishnu and Maata Laxmi in the heart of Shri Hanuman. This will elevate your pooja status. Vayu is the Mukhya Prana without which nothing is possible. And Shri Hanuman is Vayu incarnation. Sri Rama and Sri Krishna both had services of Vayu in the form of Hanumanji and Bheemsen. Shri Vishnu pooja is half without Vayu archana.
Preferably you should be in white clothes while you do the archana, if you want to proceed on gnana marga. For Rajasik desires, Red works well.
If you are not in the proper asana and above mentioned mode (like driving etc), recite the name of Shri Vishnu in Shri Venkatesha and Shri Trivikrama avatara. "Shri Venkateshaya/Trivikramaya Namah" is best to do.
The Bhava is very important. At the same time, it is essential that Shuchi/Ashuchi related precautions are also followed, as much as possible. During emergencies, Lord gives an exception. But the emergencies should be real emergencies only and not routine mismanagement of time or events.
This is to ensure that you get Purna fal of your Japa and do not incur any doshas alongside the punya you gain.
Last but not the least, do ask for forgiveness at the end of the Japas. The almighty is Karunasagar. You can rest assured leave the results to him.

Then, what is the best asana for this? You know in US, we don't have pooja rooms. So, kindly guide me as to the best way to do this.
Also, as Ramananji said, my main intention is to chant SVS atleast once every day. I have managed to do it without fail for the last 4.5 years.
Please guide me about the right way of doing this.
