Wow, you make things easy for someone to help!
First, I'd say that quality yixings are not mandatory for good experiences. It's also pretty easy to go crazy over various different features. Anyways, the more porous and low fired, the more each session blurs into another. The more hard fired, the less the pot will be able to influence flavors, and some do well for boosting aroma or mouthfeel. I am not a pot expert, however, I've been told that JingTeaShop: http://www.jingteashop.com/cat-jing-tea-shop-teapot.cfm
is a reputable vendors with quality teapots that you can trust to be what they are. In general, you should shop for pots in person. I use a kyusu for my shu, and I wouldn't want to put shu in my sheng pot. Some of them are funky, and I generally want heavy, dark flavors to be from my sheng.
Now, as far as tea is concerned. It sounds like you'd like various Bulangs and Mengsongs, etc, and you'd want a bit of moist age for them.
For cheaper drinking, I think tuos like this one from Origin Tea: http://www.origintea.net/pu-erh-tea/2003-xg-tuo
or tuos like the one white2tea has: http://www.white2tea.com/tea-shop/2004-jianshen-tuo/
, or lastly, younger tuos like http://www.chawangshop.com/index.php/20 ... -250g.html
Mouthfeel is a bit trickier, as most of the things I can think of with excellent mouthfeel are expensive, like http://www.origintea.net/pu-erh-tea/2007-yqh-qi-zhong
and http://www.origintea.net/pu-erh-tea/200 ... shroom-tuo
, and if you do go with Tony for some things, I'd strongly recommend that you ask for a quote on the 2007 Wisteria Hong Yin and Lan Yin. If they haven't gone up too much, they shouldn't be too horrifically expensive. Both are dark tasting, with good body, good energy, and good qi. Given your fashion for yoga, this premium tea from white2tea might be in your wheelhouse: http://www.white2tea.com/tea-shop/2005-naka/
. I have my own quality Mengsong like this, and having a well aged tea of this type is quite...preferential, let me say.
If the order from Tea Urchin isn't complete...
I've had the Langhe '06 golden buds. It's an okay shu but overpriced. Golden buds are also a very particular taste--they're lighter than most shu, and they are really meant for aging a long while to develop a floral taste.
People have been pretty nonplussed with the 2007 Bangwei. I wouldn't suggest that one as a sample.
I've had the white paper 2006 Yiwu. It's only okay for me, because it's rather wet, and I don't think much of the original material. It's improved by breaking it up and letting it sit, and it will give a decent darkish brew.
Dayi 7572 can be gotten anywheres, and if you're looking for sampling Dayi shu, I'd recommend sampletea.com, where they have a number of them, cheap. I've had the 2008 Dayi Bulang way back in 2010, and I didn't think much of it. I'm not sure it's really worth thinking about at all compared to boutique bulang offerings. I mean, I get good feedback from the Bulang Beauty TeaUrchin has, or that New Amerykah cake at white2tea. Why bother with Dayi when it comes to single area tea?
I can't seem to get on the website right now, but the one tea that I have had reasonable satisfaction from was the 2012 Spring Xikong, made with Gao. That is worth the sampling, as well as its companion Mangzhi.
