Does a logo make me look more professional?

I have added a logo to my website http://www.rentalagreementsdiy.com.au/

I reluctantly put it at the top. I would have preferred text to stay there. It used to have the words Rental Agreements DiY with a h1 tag.

Again I am nervous as to what this change might do to my rankings. Things are getting better in all search engines. I am ranking higher and higher in google. I come up first in a variety of searches and on the front page for lots more.

I have also just booked a 4 day web marketing seminar in March. It sounds interesting. I will let you know what happens.
