Increasing the nonce size would not increase or decrease the expected block time. The block time is maintained via the difficulty adjustment algorithm, which adjusts the network difficulty according to the apparent time it took for the last 2016 blocks to be found. How quickly blocks are found can thus be used to estimate how many hashes/second the ...

If you want to move all your computational power (hash power) suppose you could just disconnect from your current pool and connect to the other one If you want to divide between different pool I suppose you could just connect to them then use a tactic of process priority to choose how much power you want to devote to each pool depending on its process, for ...

Adding more zeroes (more precisely as a prefix) to the required block hash (which is the hash of block header) makes it more difficult because you need to keep hashing the block header until you find a hash value that is less than the required maximum numeric hash value (you update the block header everytime by incrementing the nonce in it which changes the ...

I've got the answer http://www.righto.com/2014/02/bitcoin-mining-hard-way-algorithms.html: The key point is that each nonce generates a basically-random hash value. To get a lot of zeroes, you need to try an exponentially large number of nonces.
