Well those sound like ambitions goals, but they are good ones. I am one a road similar to yours. Here are my tips.
==An army is thirty is about as big as most people need and i cant see a use for an army of more then 60. But if you want go right ahead but remember the phrase, "its the way you use it, not the size that counts."
==60 with 30 mining is nice, but what about putting more time in to just a few. 20 with 60, to get into mining guild, could be MUCH better.
==How will using tarajunky's chicken killer make you an SRL member? To get in to SRL, you need scripting skills (including walking, object finding, multi-player, and anti-randoms). If you want to learn, check out the tut section. There are some truly great tuts.
==In your sig, you say 60 with 10 attack. Before you starting autoing a skill, you NEED to gain much more then 10 attack. My army is at LEAST 15-20 before mining or wood cutting. When an account reaches 30 mining, i bring it back to get to at least level 30 attack. Please trust me on this, it keeps you from being banned.
=="desktop 4gb ram 4ghz processor." processor of 4ghs is about what you want in a new computer, but 4gigs!?? You would only need what it you were autoing on several Virtual Machines at once... ah, so you DO have a good reason. If your not going to do that, why bother?
Dont know what a VM is?
Well, i hope this helps. Welcome to the community!
These are my principles. If you don't like them, well... I have others.
Since brevity is the soul of wit, I will be brief. Auto Correctly.
