I am working with OpenLayers plugin in QGIS 1.8 but I am not sure on how should I manage the CRS.
The default CRS for Google/Bing layers is WGS84/Pseudo Mercator (EPGS:3857) but I am not sure on the CRS of the new layer I want to work on.

For the Openlayers plugin, the Project CRS must be in EPSG:3857.
Your other layers can have different Layer CRS, if you have enabled On-the-fly-reprojection.
BTW, current version of QGIS is 2.4, and the openlayers plugin does not support older versions anymore.
You should create new custom CRS and assign it to your layer(s). This quick and dirty approach worked for me after reading all the posts arround here. I use QGIS 2.8.1 and metric system, as I live in Central Europe:
- import Open Layer (in my case, Google Hybrid)
- import your data (in my case, our Municipality Border)
- right click on your data layer and choose "Set Layer CRS"
- Choose "Automatic Coordinate System" - this should bring your data near to desired position (in my case, 470m too much east and 370m too much south)
Measure your x and y difference between specific point on Open Layer and that same point on your layer
Go to Settings, Custom CRS
- Click + sign to add new Custom CRS and give it a name
- Copy parameters from Suggested "Automatc Coordinate system" to new one and alter last digits in +x_0=... and +y_0=... section with values you measure as difference in x and y direction before.
- Click OK to save it and right click on your Layer again - choose "Set Layer CRS".
- First choose previous CRS and click OK, then your new CRS and click OK.
- Your Data should align with Open Layer, otherwise experiment with settings a little more.
Maybe picture is more informative, so I attached one. Hope my approach will work for you as well.
