What kind of dollars? You can get direct flights from HKG-HND for less than US$300 with low-cost carriers, for example HK Express is selling tickets for today for US$170. Are you sure that this stopover is worth it?
2. What are my travel options to get from TPE to TSA? What bus should i take? Best mode of transportation?
There are buses 1840 and 1841. The 1840 is direct and costs NT$125, the 1841 is 10 minutes slower costs NT$83.
3. Should i convert some currency prior to going if i only plan to take the transportation and go from one airport to the other?
If you're in HK, then just change HK$50 to NT$200 at the HSBC in Terminal 2, or even one of bureaux de change on the street and then buy a small snack at TPE to get some coins for the bus fare. If you're coming from the US then bring a $10 bill and exchange it at TPE.
