Here are Perth Mint's definition of Proofs Bu's and Specimen coins,I've added a few coins to hopefully clarify things,the proofs are all on the left of the photos
 
 
Proof Coin
The very highest quality collectable coin produced by The Perth Mint.  Featuring a proof finish comprising a highly-polished table with frosted and/or coloured design elements.
Bullion Coin
A mass produced coin primarily aimed at precious metal investors. Finished with shiny design elements on a frosted table.

Specimen Coin
A collectable coin akin to a bullion coin with a frosted table, but also featuring one or more special numismatic treatments, including colour, gilding, antiquing, or the insertion of gems.

RAM's interpretations of proof and Bu,s also known as UNC/uncirculated.
 
Proof
A carefully struck coin using special dies with either a mirror‑like or matt finish. These coins are especially struck and the term is not used to describe a well‑preserved circulating coin. Proof is a method of manufacture, not a condition or grade.
  Uncirculated (UNC)
Uncirculated coins are manufactured in much the same way as circulated coins except for the following:
More attention and time is given to the preparation of the die surface finish, The coins are struck with greater pressure than the circulating coins to improve the sharpness of the design. More care and attention is applied at each step in the coining process to minimise damage, consequently a much lower production rate of about 30,000 coins per press per day is achieved. Uncirculated coins are packaged individually into plastic sleeves, presentation folders or occasionally presentation cases.

@FrostStart small and focus on a particular series that you personally like.  I started getting 1 of each series that I was considering before I committed with stacking. Although I was and still constantly adjusting, over the weeks/months my stacking goal became clearer. I've also learned a lot on the and forum especially which gold coins are good to stack . So keep learning, do your research and don't haste with your purchases and make sure you don't overpay (obviously).
Set yourself a realistic goal/target and then work out a monthly budget for your PM (precious metals) purchases. I use a percentage, for example I spend or set aside 10% of my income for PM, at the moment. I like this method because my budget can go up or down should I earn more or less (as I also work freelance). That % will hopefully change in the next couple months, when I have a better financial outlook. Some people have different ideas but this works for me.
Ive learned this method from a little book called The Richest Man in Babylon. I highly recommended this book for stackers, I think you still can find the audiobook on YouTube.
