Usually bigger tires just means accelerated wear of parts such as wheel bearings & brakes - the trans could perhaps see increased wear but who is to really say? The heavier tires can induce some handling oddities but nothing too severe. I've always understood it is a good idea to replace the brake lines with braided ones especially if you have bigger, heavier tires. The rear links, brake lines, & driveshaft will not need to be adjusted/lengthened. I did flip my BJs & I replaced my CV boots but I also fabbed up drop brackets for the diff as well. Be sure you consider lengthened rear bump stops also. I also installed the low-profile front bump stops for slightly more droop & even then the stock length brake lines were safe. I went from the tire size you have up to 32.5x11.5 & got after it in the front wheel well just so I did not have to worry about any rubbing. If I remember right, there was none.
I hope these pics help...
