I would spend my money on the Nova, restoration is big bucks and once you start modifying the Jeep the Nova project is likely to suffer.
But, to answer your question:
As far as lift brand, I like my Rubicon Express parts. For tires, I would go with Goodyear Duratracs, they are relatively inexpensive, relatively quiet, and have excellent on and off road capabilities. You might want to consider installing a set of JKS sway bar disconnects as they work well, and are as silent as the factory links, and will allow more articulation.
Since you mentioned that you don't intend to go off road very often, I would purchase a set of 29" tires, and perform some mild fender trimming. If you don't want to trim the fenders, then a set of coil spacers sized 2" or less, and a set leaf spring blocks of the same height will provide you with the space you need for slightly bigger tires. I would also recommend removing your rear sway bar, you don't really need it, and it inhibits rear articulation.
These mods are easy to perform, easy to reverse, light on the wallet, and will provide a substantial improvement over a stock XJ.
If you go bigger, keep in mind that you will need to install a slip yoke eliminator and a custom rear drive shaft, and if you plan on running taller tires you will need gears, especially since it's your daily driver, and and and....What I am trying to say is that it's a vicious cycle; a slippery slope, and a steep one at that. Keep your lift small, and if you decide to go bigger, then you can always sell your old parts as you upgrade to bigger and better things later on.
As for ordering parts, I have had good luck with Quadratec, and they will send you a free catalog tailored specifically to XJ/ZJs.
