You could switch over to a RADS or YO-Yo system after you've ascended into the crown of the tree. There are a few RADS variations but it can be set up so there is no gear change when switching from ascent to descent. Then there is the Omnicender which also provides seamless switchover from ascent to descent.
Here is one flavor of RADS, a Shunt is use up top, there is a tender line on the Shunt that releases it when you want to limb walk or descend. You can use an ID or a Grigri. Go to the \"All sizes\" link above the photo to look at more detail.

Yo-yo on New Tribe site, this variation requires taking the upper ascender off to descend

The two common methods for securing an SRT TIP:
1. Choke a backed up (Yosemite or other) running bowline or an F8 on a bight and screwlink to the branch
2. Put the rope over the branch/crotch and secure to the trunk at the base of the tree or a nearby tree. The ground anchor method is probably used more often in tree climbing, does not require isolation of the TIP and provides some rescue options for lowering an injured climber.
I don't know of any SRT specific books or video for tree climbing. If you search on the arborist websites like Buzzboard or Arboristsite you can find detailed discussions of SRT technique. Most of the tree SRT technique is descended from either big wall rock technique or caving technique, that's where you're going to find the books and video I think. Check out the Sherrill and On Rope web sites to see various SRT gear configurations.
