First answer: Yes, that's right.  The way the process works when purchasing the IPOs was:

1. User generates their own unique wallet address.
2. User deposits into the unique address and waits for confirmations.
3. User clicks on "IPO" -> "Purchase" links in the web-based portal and chooses how many shares they want.
4. Once the user purchases the shares, it then sends the funds to the main holding account.

This is why you would see so many transactions for that address in that page, as each movement of the coins generates a unique transaction.

Second: The reason there is an IPO, is because we have intentions to hire outside developers to help out get some of our projects out the door.  As we're still establishing our community, these funds have not been moved.  We do have an IRC channel called #105shareholders on the freenode network which we encourage all shareholders to take part in when they can.  Once we're ready, we'll begin asking for our IPO coin holders to vote where they would prefer the funds be used.  Once the voting has completed, then the funds will be spent.  10-5 is operating as its own entity controlled by the 10-5 team, and the IPO share holders.  If any IPO shareholders are really that concerned, I have no problem returning the exact amount they sent us and revoking their IPO coins.  Unlike the many different IPO coins developed, we have had a purpose all along and we've expressed this several times in our web site, IRC channels and on bitcointalk.  I am not denying for a second that the other coins (quite a few to name) have been worthwhile investments.  Once 10-5 starts receiving profits, the IPO holders will then begin receiving dividends of the earnings we make.  If you would like to know more about what we're developing and release dates, we'll be able to provide that also.

Thanks
