Halo Moon's advice is spot-on, dont skimp on fittings or insurance, even if you have to delay buying the type 9 and grind a bit more in the t7 to buy everything from the start.
Your Indiction rate from NPC pirates has probably been quite low up to now, my rate would average 2-3 in several hours of playing, well, once I bought my T9 this went through the roof for the first 4-5 hours, where my indiction rate sky-rocketed to about 6-8 an HOUR, I even had three indictions just going to one station! This was pre-1.2, where I only had 1 npc attack me each time. Things have changed now that we have Wings. So I would recommend you use some of those empty Utility bays on the t9 and put in some Shield Boosters.
Also, since flying the T9 is so much different to anything else you've flown previously, until you get used to it's slow handling you could install a Docking Computer to help you through the Letter Box opening, until at least you have enough spare credits that a crash or two wont bankrupt you. The insurance will be over 5 million credits. Accidents happen, especially when tired.
Aside from all this, I have to save I love flying the T9, it's got character and lets you take your time while still earning you a ton of credits.
