Settling in and Questions for you

Now that I am going to be settled in at home for the next few months, I hope to finally catch the blog up with fun pictures and tales from my trips this year.
There are also some exciting changes on the home front, as we finally got our new carpet installed in the basement on Monday, after two months with one third of our home unusable. It will be great to get furniture out of the garage and into the new space (and to get my car into the garage again, finally!!....it really stunk to have to clean snow off my car last month; I'm out of practice since the car lived inside most of last year).
Currently, I also have high hopes of doing some painting. This week's new home based challenge is choosing a new water heater and who will install it. Not decorative, I know, but it's the reality of being a home owner and it does offer some interesting tax rebate opportunities as we become more energy efficient. Does anyone have experience with purchasing water heaters out there? Does an energy efficient heater = shorter showers because we will run out of hot water faster? And I'm debating hiring a plumber vs using Lowe's for istallation. The plumber was very nice but almost $400 more expensive. Lowe's has a couple of cons on the list but plenty of pros, as well.
And finally, I am also interested in merging my travel life into my home life. How do I aim to do this? I'm going to hang a hammock!!!!! It's so symbolic to me of relaxation (and I helped the hammock man in Costa Rica weave part of one, which was really cool). Not being the most spatially inclined person, I am a bit overwhelmed by the finding of studs in a condo basement to secure my hooks into. And if I am unable to hang the hammock in the basement as I dreamed of, where else can a hammock live inside? PS, Hubby told me to hang it in the garage. Really?? Am I really going to hang next to my car in the freezing cold reading a book? Now you probably understand why I take girl trips:)
